A study on the thermophysiology of metriorhynchids, as indicated by the oxygen isotope composition of the tooth enamel phosphate, is published by Séon et al. (2020). [29] Fossil material of two large-bodied metriorhynchids is reported from lower Kimmeridgian sediments in Bavaria and Baden-Württemberg by Abel, Sachs & Young (2020), who ...

A study on the anatomy, taphonomy, environmental setting and phylogenetic position of Halszkaraptor escuilliei is published by Brownstein (2019); [210] the study is subsequently criticized by Cau (2020). [211] A study on a fossil lizard found in the abdomen of a specimen of Microraptor zhaoianus from the Lower Cretaceous Jiufotang Formation ...
Scleromochlus taylori was about 181 millimetres (7.1 in) long, with long hind legs; it may have been capable of four-legged and two-legged locomotion. Studies about its gait suggest that it engaged in kangaroo- or springhare-like plantigrade hopping; [2] [3] [4] however, a 2020 reassessment of Scleromochlus by Bennett suggested that it was a "sprawling quadrupedal hopper analogous to frogs."
While these are all common attributes of bird tracks, there’s just one problem—true birds don’t arrive in the fossil record until some 60 million years later, in the Late Jurassic.
Three dinosaur fossils from the Jurassic period will go under the hammer at a London auction on Thursday, with price estimates of millions of dollars. Christie's is offering the skeletons of an ...
A study on assemblages of nesting ring-billed gulls, California gulls, American white pelicans and double-crested cormorants at Bowdoin National Wildlife Refuge (Montana, United States), evaluating their utility as taphonomic models for interpreting nesting sites of fossils archosaurs, is published online by Ferguson, Varricchio & Ferguson ...
Arizonasaurus was a ctenosauriscid archosaur from the Middle Triassic (243 million years ago). [1] Arizonasaurus is found in the Middle Triassic Moenkopi Formation of northern Arizona. A fairly complete skeleton was found in 2002 by Sterling Nesbitt. The taxon has a large sailback formed by elongated neural spines of the vertebrae.
