In a recent paper, community-held archival material was used to evaluate the palaeo-biology of dinosaur track-makers from the 'fireclay caverns' of Mount Morgan. With the ensuing interest, community members disclosed additional photographic documentation of Mount Morgan dinosaur tracks. The described theropodan and ornithischian tracks are consistent with the known Mount Morgan ichnofaunal record, while evidence of Anomoepus track-makers walking with the atypical plantigrade pedal posture has not been previously documented in Australia.

The Callide Basin Lower Jurassic units had been noted two decades ago as having preserved dinosaur ichnites, however, none had been shown or described at that time. The current study is the first to describe a dinosaur track from this region, a fossil collected over a decade ago from an overburden dump from the Callide Mine (Dunn Creek mine area). The track morphologically resembles those of a large Anomoepus-like 'Anomoepid' and confirms previously unsubstantiated reports of ornithischian tracks at the location. The tracksite represents the third Early Jurassic dinosaur fossil site in Australia. All of these are tracksites restricted to Central Queensland with the Biloela track the only known Australian Jurassic dinosaur print preserved as a concave epirelief (impression). The find contrasts with earlier statements that the open-pit mining practices make the discovery of dinosaur tracks unlikely. Instead, the extraction of overburden rock has the potential of re-discovering additional fossil track-bearing strata. It is hoped that there will be further discoveries made within the region.

Dinosaur tracks associated with coal-mines of the Middle to Upper Jurassic (Callovian–Tithonian) Walloon Coal Measures (Clarence–Morton Basin) have been reported on more than any other track-bearing formation in Australia, yet due to the brevity of ichnological information, remain poorly known. All these tracks were found in sediments directly above coal seams in the ceilings of subterranean mines. This style of mining ceased more than a quarter of a century ago, and with many of the original mines having been back-filled or closed, ichnological investigations are restricted to the study of museum specimens and archival photographs. Here, we consolidate data from the literature, present previously unpublished archival photographs, and show the 3D topography of all accessioned track specimens from the Walloon Coal Measures. We recognise eleven track-bearing sites, most of which produced large (length of 30–50 cm) and very large (length greater than 50 cm) sized theropod tracks, including Australia's largest carnivorous dinosaur footprint (79 cm long). The domination of theropod tracks is unique among Australian dinosaur tracksites. In light of the absence of near coveal body-fossil candidates, the Walloon Coal Measures ichnofaunal assemblages fills significant gaps in our understanding of Australia's Jurassic dinosaur fauna.

The ichnological and palaeobiological interpretation of the first dinosaur tracks described from the Lower Jurassic (Sinemurian) Razorback beds, anthropogenic 'fireclay caverns' of Mount Morgan, Australia, is reviewed. This track sequence of two size categories has been widely accepted as having been formed by a theropod walking in an uncharacteristic quadrupedal stance. However, the morphology of the purported manus impression remained ambiguous due to the poor reproduction quality of the original image data. Here, we present previously unpublished archival photographic and replica material of this track surface. These clearly show the morphological details of the track series that are consistent with registration by two different sized bipedal track-makers. Overall, our findings illustrate that retained archival data can be pivotal in the resolution of palaeoichnological obscurities. [ABSTRACT FROM AUTHOR]
