The monobathrid camerate crinoid Macrostylocrinus bornholmensis Laursen has an unfortunate history. It was published in a journal not commonly consulted by echinoderm workers and, worse, in time of war; written in a language not in common use for crinoid studies; and described by a stratigrapher, not an expert on pelmatozoans. These and other factors combined to ensure that M. bornholmensis has not been reassessed since it was first described almost 80 years ago, despite belonging to a genus well-known from the Lower Palaeozoic. Macrostylocrinus bornholmensis is Llandovery (Telychian) and not Wenlock as has been reported elsewhere. Diagnostic features include a column that does not bear radices close beneath the cup; a heteromorphic mesistele with five orders of regularly inserted internodals; three basal plates; smooth thecal plates with central folds following rays; and ten pinnulate free arms that are biserial distally. Macrostylocrinus bornholmensis is distinctly different in morphology from well-known, congeneric species described from the Lower Palaeozoic of northern Europe.

Crinoids and brachiopods are described from the Silurian Uzyan Formation of the Zilair Zone in the southern Urals. The occurrence of the graptolites Coronograptus praedeubeli suggests a late Homerian (Wenlock) age for the strata. A new disparid crinoid, Cicerocrinus gracilis Donovan sp. nov., is the oldest known member of this genus. It has a long, flexible and homeomorphic column, and a tall bryozoan palaeontology terminology (IBr2) (second primibrachial) axillary. All species of Cicerocrinus described previously have been limited to the Ludlow of the British Isles, Sweden and Estonia, and the Pridoli of Estonia. The poorly preserved brachiopod fauna is represented by small atrypid (Atrypa? sp.) and dalmanellid brachiopods (Levenea? sp.). The reported assemblage generally inhabited deep-water environments.

Abundant marine macrofossils are present in graphitic marbles and calc-silicate schists belonging to the Veleta nappe of the Nevado-Filábrides Complex (Internal Zones o the Betic Cordillera, SE Spain), in whet is called the Águilas tectonic arc. These fossil assemblages are dominated by crinoids, followed by minir cephalopods, brachipods, rugose corals, and putative sections of trilobites. In addition to these confidently identified groups, there are other sossil represented, but deformation and extensive recrystallization have destroyed anatomical characterers, hampering their taxonomic identification. Among the crinoids, the columnal parataxa Pentagonopentagonalis (col.) and Bystrowicrinus (col.) have been recognized. Planispiral cephalopods, assigned to either primitive ammonoids attributable to the order Agoniatitid (one of them being a possible member of the family Mimosphinatidae, or coiled nautilids, as well as orthoconid sections of possible orthoceratids of bactritids are present. Finally, there are rugose corals attributable to the family Phillipsastreidae, possibly Peeckiell. Among the remains with obscure taxonomic assignment, we recognize possible laminar calcareous algae and benthic foraminifers. Tinally, irregular, massive structures showing a rough laminar organization and longitudinal tubes with rounded sectiona are found in some black marble beds. These can be identified either as possible chaetetids or bryozoans. The report of these taxa has limited the rocks studied to the Emsian, late Early Devonian., Los mármoles grafitosos y calcoesquistos pertenecientes al manto del Veleta del Complejo Nevado-Filábride (Zonas Internas de la Cordillera Bética, SE de España) del denominado arco tectónico de Águilas contienen un abundante registro de macrofósiles marinos. Dichos fósiles han estado sometidos a un proceso de metamorfismo y deformación y, aun así, y, en determinados casos se han preservado de forma excepcional. Las asociaciones fosilíferas están dominadas por crinoideos seguidos en menor proporción de cefalópodos, braquiópodos, corales rugosos y secciones de trilobites. Además de estos grupos, que han sido identificados con un alto nivel de fiabilidad, hay otros que no han podido ser clasificados con certeza debido a que la intensa deformación y recristalización que afectó a las rocas han obliterado los caracteres anatómicos diagnósticos. Por tanto, su identificación taxonómica es más complicada. Entre los crinoideos, se han identificado dos parataxones columnares Pentagonopentagonalis y Bystrowycrinus. Se han reconocido cefalópodos planiespiralados, identificados como ammonoideos primitivos atribuibles al orden Agoniatitida (uno de ellos posiblemente pertenece a la familia Mimosphinctidae) o nautílidos planiespiralados, al igual que secciones ortocónidas de posibles ortoceratítidos o bactrítidos. Finalmente, los corales rugosos corresponden a la familia Phillipsastreidae, entre ellos al género Peneckiella. Entre los restos no identificables hemos reconocido posibles algas calcáreas laminares y foraminíferos bentónicos. Por último, en los niveles de mármoles grafitosos se encuentran unas estructuras masivas e irregulares que muestran una laminación horizontal y tubos verticales de sección redondeada. Pueden ser tanto posibles chaetétidos como briozoos. La asociación de fósiles estudiada permite limitar la edad de las rocas estudiadas al Emsiense (Devónico inferior)., Ministerio de Ciencia e Innovación (MICINN), Junta de Andalucía, Depto. de Geodinámica, Estratigrafía y Paleontología, Fac. de Ciencias Geológicas, TRUE, pub

Ensis americanus (Binney) is an alien razor shell living infaunally in the southern North Sea. It is encrusted postmortem by the acorn barnacle Balanus crenatus Brugiere. A remarkable shell of E. americanus was found densely infested by a single spatfall of B. crenatus on the inner and outer surfaces of both valves. The ligament was still attached and was pliant when collected, indicating that infestation was soon after death, probably only weeks or months before it was collected. The evidence of this specimen argues strongly against the common received wisdom that borings or encrustations on the inner surfaces of disarticulated fossil bivalves are an indication of a relatively long postmortem residence time on the seafloor.

A collection of numerous crinoid pluricolumnals from the uppermost Darriwilian (Middle Ordovician) of Tibet were derived from one biological species of crinoid. The specimens were collected from well-lithified, bioclastic shelf limestones of the upper part of the Lower Chiatsun Group, Pygodus serra Biozone; coeval rocks of similar lithology outcrop at the summit of Everest. A new crinoid morphospecies, Segmentocolumnus (col.) hanshessi, is tentatively considered a ‘stem-group cladid’, perhaps a dendrocrinid. The proxistele is broad and pentagonal in section with a broad, pentagonal axial canal; the mesistele of similar gross morphology is more slender with a regularly heteromorphic column and a similarly wide axial canal; the dististele is a terminal dendritic radice with a pentastellate axial canal. In the mesistele, the meric sutures correspond to the centres of the sides of the column, but in the dististele they occur in the angles. This range of morphologies would have led to their inclusion in at least two morphogenera if they had not been closely associated; as they belong to a single biological species, they have been ‘lumped’ together herein. This is a rare contribution to our knowledge of the early crinoids from a region outside Europe and North America.

In the last decade, a rebirth in interest of Jamaican fossil crustaceans has occurred. A summary of known material is provided together with some indications of the directions that future studies should take.
