Otozoum ("giant animal") is an extinct ichnogenus (fossilized footprints and other markings) of sauropodomorph dinosaur from the Late Triassic-Middle Jurassic sandstones. Footprints were made by heavy, bipedal or, sometimes, quadrupedal animals with a short stride that walked on four toes directed forward. [ 1 ]
In 2016 Molina-Perez and Larramendi based on the 45 cm (1.48 ft) long footprint estimated the size of the animal at 8.4 meters (27.5 ft) and 600 kg (1.323 lbs). [8] Another 60.5 cm (1.98 ft) long footprint belongs to an 8.1 meter (26.6 ft), 1.1 tonne (2.425 lbs) individual, that was very similar to Sinosaurus triassicus .
When referring to trace fossils, the terms ichnogenus and ichnospecies parallel genus and species respectively. The most promising cases of phylogenetic classification are those in which similar trace fossils show details complex enough to deduce the makers, such as bryozoan borings , large trilobite trace fossils such as Cruziana , and ...
The confusing history of dinosaur footprints means many kinds of theropod tracks have been put into the Megalosauripus ichnogenus, [4] even though they were an entirely different ichnospecies. This makes it hard to piece together what exactly is Megalosauripus , and what is not.
The hand and foot imprints are not particularly distinct. [7] D. didactylus tracks are based on similar tracks, but where the imprints of all but two digits are faint. [2] Dromopus tracks have been ascribed to lizard-like reptiles, including the diapsid Araeoscelidia and the parareptilian Bolosauridae. [1] [8] [9] Paleontology portal

Diplocraterion is an ichnogenus describing vertical U-shaped burrows having a spreite (weblike construction) between the two limbs of the U. [1] [2] The spreite of an individual Diplocraterion trace can be either protrusive (between the paired tubes) or retrusive (below the paired tubes). [3] Some ichnospecies have both types (e.g ...
Wakinyantanka are large, tridactyl, and bipedal pes prints, with the middle (third) toe being the longest (mesaxonic), typical of theropod footprints. The digits of Wakinyantanka are long and slender, and are widely divaricating so that the prints are roughly as wide as they are long, averaging between 55–60 centimetres (22–24 in) long and 60 centimetres (24 in) wide.
