The Viperidae is the most speciose family of Brazilian venomous snakes, with 33 known species. Although the family is well defined cladistically, there are few studies concerning the postcranial skeletal morphology, and only a single vertebral synapomorphy has been proposed. The paucity of knowledge on postcranial morphology poses challenges for the study of the Brazilian viper fossil record since most fossils consist of disarticulated and isolated vertebrae. Currently, Bothrops and Crotalus are the only vipers recognized in the Brazilian fossil record. Nonetheless, interspecific differentiation based on vertebral material is hampered due to the lack of comprehensive detailed anatomical data. We compared the trunk vertebrae of extant specimens of Crotalus and Bothrops using two-dimensional geometric morphometrics to obtain discriminant data about their vertebral morphology. We examined the trunk vertebrae of 20 vipers, 10 Crotalus, and 10 Bothrops and performed macroscopic analyses and measurements and landmark-based, two-dimensional geometric morphometric analyses. We sought to identify structural differences between the genera and to assess morphological variation along the spine. Most differences in the trunk vertebrae between Crotalus and Bothrops occurred in the length of the neural spine, the parapophyseal processes, the prezygapophyseal processes, and in the angle on the prezygapophyses. However, when we accounted for intracolumnar variation, differentiation is hampered. We expect our results will serve as a starting point for future studies of viperid vertebrae and aid paleontologists in accurately identifying fossil vipers. [ABSTRACT FROM AUTHOR]

Publisher Copyright: Copyright © 2022 The Institute of Electronics, Information and Communication Engineers. The Bauru Basin bears one of the best sampled tetrapod paleofaunas of Brazil, with about 70% of this diversity collected from its deposits in São Paulo. Its fossils are known since the beginning of the 20th century, coming from all stratigraphic units of the Basin cropping-out in the state, i.e., Santo Anastácio, Araçatuba, Adamantina (alternatively divided into Vale do Rio do Peixe, Presidente Prudente, and São José do Rio Preto formations), and Marília formations. Identified taxa include rare anurans, mammals, and squamates, an important set of testudines, theropods (including birds), and sauropods, in addition to one of the most diverse crocodyliform faunas known worldwide. This congregates more than fifty unique taxonomic entities, including 42 formally described species. Based on biostratigraphic correlations (including tetrapods), on few absolute ages, and other sources of evidence, the Bauru Basin deposits in São Paulo seem to be chronologically restricted to the Late Cretaceous, but further investigation is much needed. Finally, the history of research with such fossils highlights the importance of public funding for research and decentralization of university education for the advancement of science. publishersversion published

The extinct fossil snake Boavus occurs in early–middle Eocene localities in the United States. Four species are currently recognized, but until now, no formal phylogenetic analyses have been conducted to test its relationships within snakes. Here, we provide an osteological redescription and systematic revision of the genus, accompanied by phylogenetic analyses using multiple methods. Based on new morphological information obtained through first-hand observation and published descriptions, differences between Boavus occidentalis, B. agilis and B. affinis can be ascribed to normal intracolumnar vertebral variation, making the latter two junior synonyms of the first species. Our phylogenetic analyses retrieved Boavus within crown-Booidea as an early booid but outside of Boidae. A morphological and molecular analysis of booids, with dense taxon sampling including fossil and living forms, results in a new booid phylogeny. Boavus, along with other fossil booids from Europe (Eoconstrictor, Messelophis, Rieppelophis, Rageryx), suggests that crown-Booidea likely diverged earlier than estimated by some molecular studies (∼45.4 Ma).

CHILABOTHRUS STANOLSENI COMB. NOV. (FIG. 2; TABLE 2) Diagnosis: An extinct species of Chilabothrus from the early Miocene of North America, characterized by the following unique vertebral features shared among the referred material: thick zygosphene with a slight prominence on its mid-portion in anterior view; zygosphene roof with a crenate anterior edge, with its median lobe weakly developed and bounded by rounded lateral lobes of the zygosphene articular facets; irregular presence of paracotylar foramina, neural foramina occurring in format of small pits, and variable presence of several foramina distributed in the parazygantral area; neural spine perpendicular to the vertebral centrum, with an elliptical shape in cross-section; articular facet of the zygosphene oval in shape and strongly oriented anterolaterally; vaulted neural arch slightly depressed dorsoventrally in its median portion; deep interzygapophyseal ridges forming a ���U��� shape; and a shallow posterodorsal notch length that does not exceed more than the half the distance between the pre- and postzygapophyses. Holotype: MCZ 1977 partum, an anterior precloacal vertebra. Referred specimens: Six precloacal vertebrae representing the previous paratypes of MCZ 1977 (identified by the same catalogue number), comprising five mid-precloacal vertebrae and one anterior precloacal vertebra. MCZ 1978, four precloacal vertebrae (same catalogue number), including one mid-precloacal vertebra (previously the holotype of N. barbouri) and three partial mid-precloacal vertebrae. MCZ 2417, three mid-precloacal vertebrae. AMNH FARB 7627, two-midprecloacal vertebrae. Type locality and age: Thomas Farm deposit, Gilchrist County, Florida. Hawthorne Formation. Early Miocene, corresponding to the Early Heminfordian Land Mammal Age (LMA), c. 18.5 Mya. (Hulbert, 2001; MacFadden, 2001; Steadman, 2008; Beatty, 2010). Description: All vertebrae of MCZ 1977, MCZ 1978, MCZ 2417 and AMNH FARB 7627 are well preserved and assignable to the same taxon. In anterior view, the zygosphene is thick and wider than the cotyle (zw> ctw). The mid-ventral region of the zygosphene exhibits a convexly projecting border, being more marked in the midprecloacal vertebrae. The prezygapophyses are slightly inclined above the horizontal axis (~10��), showing a higher inclination in the mid-precloacal vertebrae (~13��), whereas they are angled lower in the anterior elements (~10��). A small prezygapophyseal process is observed in some of the vertebrae, extending a little beyond the edge of the articular facet of the prezygapophyses. In the anterior precloacal vertebrae, the dorsoventral height of the neural canal is greater than the transverse width (nch> ncw), whereas the opposite condition is observed in the mid-precloacal elements (ncw> nch). The cotyle is oval in general shape, being slightly flattened dorsoventrally (ctw> cth) in all specimens with the exception of MCZ 1978, in which the cotyle is subrounded (ctw ~ cth). Lateral to the cotyle, there is a paracotylar fossa that in some specimens is associated with paired foramina (i.e. MCZ 1978 and some paratypes of MCZ 1977). The paradiapophyses are strongly oriented lateroventrally with both articular facets clearly differentiated: the diapophyseal articular facet has a strongly projecting convex edge, whereas the parapophyseal articular facet is concave (see the paratypes B, C of MCZ 1977). Hol. denotes the specimens previously attributed to the holotype material of Neurodromicus; letters denote an individual vertebra specimen; and dash denotes structure not measured due to the preservation of the specimen. Morphological structures abbreviated in the Anatomical abbreviations��� section. In posterior view, the neural arch is vaulted in all vertebrae. The neural spine of the holotype of MCZ 1977 is broken at its dorsal tip, whereas a neural spine is not preserved on MCZ 1978. In the paratypes C and D of MCZ 1977 (Fig. 3) and one specimen of MCZ 2417 (Fig. 4F), on which the neural spines are entirely preserved, this process is thick and rises from the midportion of the neural arch. The zygantrum is wide, deep and internally bears a set of paired zygantral foramina on each side of the vertebra. External to the zygantrum, several small foramina are present in the form of small pits distributed along the parazygantral area (see holotype of MCZ 1977 Fig. 2A, B and paratypes B, D of MCZ 1977 Fig. 3B, D). The postzygapophyses are slightly inclined above the horizontal axis (~10��) in the anterior precloacal vertebrae, whereas they are nearly horizontally oriented in the mid-precloacal specimens. The condyles of all specimens are wider than high (cow> coh), except for one specimen of MCZ 1978, which is rounded in shape (cow ~ coh). In lateral view, the neural spine is high, anteroposteriorly short and bears a straight dorsal edge. The articular facet of the zygosphene is elliptical in shape and anterolaterally orientated. Lateral foramina are present on the mid-portion of all preserved vertebrae. The posterior region of all centrum is characterized by a marked precondylar constriction. A well-defined haemal keel is present on the ventral surface of the mid-precloacal vertebrae, rising from the ventral margin of the cotyle and extending anteroposteriorly to reach the precondylar constriction, not extending beyond the condyle. The ventral surfaces of the centrum of the precloacal anterior vertebrae do not possess a haemal keel, having instead a hypapophysis. Although broken in the holotype of MCZ 1977 (Fig. 2A, B) and the paratypes B, D of MCZ 1977 (Fig. 3B, D), this structure was clearly developed beyond the posterior margin of the condyle. In dorsal view, the fossils are wider than long (pr���pr> pr���po). The prezygapophyses of the anterior vertebrae are oriented anterolaterally, whereas the mid-precloacal specimens display a nearly transverse orientation. The articular facets of the prezygapophyses are oval-shaped in morphology and longer anteroposteriorly than mediolaterally wide (prl> prw). The anterior edge of the zygosphene displays a crenate morphology, whereby its convex lateral lobes are separated by a smaller median projection (= median lobe sensu Auffenberg, 1963), which does not extend beyond the anterior margin of the laterals lobes. A set of paired parasagittal ridges (sensu Hsiou et al., 2014) extend anteroposteriorly along the roof of the neural arch, beginning on the lateral surfaces of the zygosphene and disappearing just short of the posteriormost edge of the neural arch (Fig. 2B, D). The parasagittal ridges are more pronounced on the mid-precloacal vertebrae than the anterior elements. The neural spine is thick with an ellipsoidal shape in cross-section, although the neural spine of the anterior vertebrae is comparatively thin relative to the mid-precloacal elements. Some specimens possess small neural foramina (= paraespinal foramina sensu Teixeira, 2013) just lateral to the neural spine. These features (similar to the several foramina in the parazygantral area) occur as either small singleton pits or as paired intrusions located on either side of the longitudinal axis of the neural arch, (e.g. the paratype D of MCZ 1977 (Fig. 3D) and paratypes of MCZ 1978 (Fig. 5). The interzygapophyseal constriction extends from the prezygapophysis toward the postzygapophysis. In the anterior vertebrae, this constriction is relatively anteroposteriorly short, whereas the mid-precloacal vertebrae exhibit a deeper constriction. The posterodorsal notch is relatively shallow in all vertebrae, and does not reach half of the length of the distance between the pre- to postzygapophyses (pnl Identification and comparisons: All specimens analysed here share with Boinae the following vertebral features: dorsoventrally high, mediolaterally wide and anteroposteriorly short vertebral built; a vaulted neural arch that is wider than the length of the vertebral centrum (naw> cl); well-developed neural spine; thick zygosphene; short prezygapophyseal process; presence of a posterodorsal notch; inclination of the prezygapophyseal articular facets lower than 15��; presence of paracotylar foramina; well-developed precondylar constriction; presence of hypapophyses on precloacal anterior vertebrae; and a haemal keel on mid-precloacal vertebrae (Rage, 1984, 2001; Lee & Scanlon, 2002; Szyndlar & Rage, 2003; Hsiou & Albino, 2009). Among the boines, the Thomas Farm fossils specimens strongly differ from the following genera: (a) Eunectes, which presents vertebrae that are markedly larger, wider and more robust; possesses a deeper posterodorsal notch; higher projected parasagittal ridges; and a median tubercle between the neural canal and the zygosphene roof; (b) Corallus, which presents a lower neural spine; higher degree of vaulting of the neural arch; and completely horizontally orientated prezygapophyses; and (c) Boa, which is discussed in greater detail below (see Discussion). The specimens described herein share with the genus Epicrates the following vertebral features: a thick zygosphene with a protuberance on its mid-portion in anterior view; zygosphene roof with an anterior edge characteristically crenate or entirely straight in dorsal view; irregular presence of paired paracotylar foramina, neural foramina and several foramina occurring in the form of small pits in the parazygantral area; neural spine in elliptical shape in cross-section; articular facet of the zygosphene oval in shape and oriented anterolaterally; vaulted neural arch depressed dorsoventrally in its median portion; interzygapophyseal ridges forming a ���U��� shape; and shallow posterodorsal notch length that does not exceed more than half of the distance between the pre- and postzygapohyses (pnl Epicrates was considered a monophyletic genus that shared a sister-group relationship with Eunectes. However, subsequent investigations into the evolutionary relationships of Epicrates have suggested potential paraphyly (based on both molecular and morphological data) with respect to the insular forms from the West Indian island complex (Epicrates sensu lato) (Sheplan & Shwartz, 1974; Kluge, 1988b, 1989; Burbrink, 2005; Noonan & Chippindale, 2006). Recently, Reynolds et al. (2013) undertook the most comprehensive study of the relationships of Epicrates, proposing the monophyly of the insular West Indian boid forms and formalizing the clade Chilabothrus, which split the insular forms of ��� Epicrates sensu lato ��� from the mainland (Epicrates sensu stricto + Eunectes) and suggested divergent biogegographical and evolutionary histories for these groups. Despite repeated suggestions of paraphyly, none of the previous works demonstrated explicit morphological differences between the axial skeletons of Epicrates and Chilabothrus. Although at a generic level these genera share a similar combination of vertebral features, there are nonetheless subtle differences that allow for confident referral of the Thomas Farm material to Chilabothrus. These traits can be identified via direct comparison with extant osteological material (Fig. 6). The main differences between these genera can be recognized via the neural spine morphology, the zygosphene and in the consistently greater meanaverage sizes of the vertebral measurements of Chilabothrus (Table 2 cf. Teixeira, 2013). Epicrates is typified by a high and slender neural spine (Fig. 4G, H), whereas in Chilabothrus the neural spine is low, nearly perpendicular in relation to the vertebral centrum and is more robust (Fig. 4A���C). In dorsal view, both genera display an elliptical-shaped neural spine in cross-section; however, in Chilabothrus the neural spine is proportionally wider than that observed in Epicrates (Fig. 4I���K). Although the Thomas Farm fossils vary in preservational quality, the completely preserved neural spines of the paratypes of MCZ 1978 (Fig. 5), MCZ 1977 (Fig. 3), as well as one of the vertebrae of AMNH FARB 7627, suggests that these fossils share a unique neural spine morphology with extant members of Chilabothrus (compare Fig. 4A���C with D and F). The neural spines of both groups are nearly perpendicular in relation to the vertebral centrum, shortened anteroposteriorly and appear transversely thickened in dorsal view. These combined neural spine characters differ from the observable morphology of Epicrates (Fig. 4G, H, K). We also note differences in zygosphene shape variation that are potentially useful for the taxonomic differentiation between Epicrates and Chilabothrus: In dorsal view, the zygosphene of Chilabothrus shows the typical crenate morphology; however, it is worth noting that the median lobe is prominent, broad and characteristically convex (Fig. 7). In contrast, the vertebrae of Epicrates show marked variation regarding the development of the median lobe of the zygosphene in dorsal view, ranging from a straight border in which the lobe itself is absent, to the moderately crenate condition and, even, the condition in which the median lobe exceeds the height of the lateral lobes of the articular facets of the zygosphene (Fig. 7) (Teixeira, 2013). The morphology of the lateral lobes of the zygosphene articular facets also differs among these two genera, with Epicrates having triangularshaped lateral lobes in dorsal view (Fig. 7), whereas those of Chilabothrus are rounded (Fig. 7). There are also some differences in the zygosphene median lobe: in Chilabothrus the morphology of the lobe is characteristically broad and convex, whereas in Epicrates this same process, while also convex, is more ���triangular��� in shape with a compressed anterior apex (compare the two morphologies in Fig. 7). The Thomas Farm material differs distinctly from these two genera, with the median lobe weakly developed and neither reaching nor exceeding the lateral lobes of the zygosphene articular facets (compare the figures with the extant species: Fig. 6A���C; Fig. 4B, C; Fig. 7; Fig. 8A, C, D, F, G). In summary, the material from Thomas Farm is assignable to the genus Chilabothrus with respect to the following exclusive combination of vertebral characters: (1) zygosphene with the anterior border crenate in dorsal view with a projection of the median lobe between the rounded lateral lobes of the articular facets of the zygosphene; and (2) neural spine shortened anteroposteriorly, nearly perpendicular in relation to the vertebral centrum, being ellipsoidal shaped and thick. Moreover, here we erect the new combination Chilabothrus stanolseni comb. nov., which represents a hypothetical radiation of extinct species of Chilabothrus into the early Miocene of North America. Additionally, Chilabothrus stanolseni comb. nov. can be identified as a distinct species via a single autapomorphic character: the presence of a weakly developed median lobe, distinct from all conditions observed in the extant genus (see Figs 4, 7, 8). In this respect, all material previously assigned to the species Pseudoepicrates stanolseni is synonymized with Chilabothrus stanolseni comb. nov., Published as part of Onary, Silvio & Hsiou, Annie S, 2018, Systematic revision of the early Miocene fossil Pseudoepicrates (Serpentes: Boidae): implications for the evolution and historical biogeography of the West Indian boid snakes (Chilabothrus), pp. 453-470 in Zoological Journal of the Linnean Society 184 (2) on pages 456-463, DOI: 10.1093/zoolinnean/zly002, http://zenodo.org/record/5715021, {"references":["Hulbert RC. 2001.

CHILABOTHRUS DUM��RIL AND BIBRON, 1844 (SENSU REYNOLDS ET AL., 2013) Remarks: The genus Chilabothrus comprises a clade of endemic extant insular boa snakes from Central America, and is supported by both morphological characters and molecular data (Sheplan & Schwartz, 1974; Tolson, 1987; Kluge, 1988b, 1989; Burbrink, 2005; Noonan & Chippindale, 2006; Reynolds et al., 2013; Pyron et al., 2014). It is represented by 12 species and 14 subspecies distributed throughout the Bahamas, Turk and Caicos Islands, and the Greater Antilles (Cuba, Porto Rico, Hispaniola and Jamaica) (Reynolds et al., 2013; Pyron et al., 2014; Reynolds et al., 2016)., Published as part of Onary, Silvio & Hsiou, Annie S, 2018, Systematic revision of the early Miocene fossil Pseudoepicrates (Serpentes: Boidae): implications for the evolution and historical biogeography of the West Indian boid snakes (Chilabothrus), pp. 453-470 in Zoological Journal of the Linnean Society 184 (2) on page 456, DOI: 10.1093/zoolinnean/zly002, http://zenodo.org/record/5715021, {"references":["Sheplan BR, Schwartz A. 1974.
