A study on the evolution of tooth complexity in squamates, based on data from extant and fossil taxa, is published by Lafuma et al. (2021). [21]A study on the diversity of jaw sizes, lower jaw shape and morphology of teeth in Cretaceous squamates is published by Herrera-Flores, Stubbs & Benton (2021), who interpret their findings as indicating that a substantial expansion of ecomorphological ...
The geologic time scale, proportionally represented as a log-spiral with some major events in Earth's history. A megaannus (Ma) represents one million (10 6) years.. The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth.
A study on the phylogenetic relationships and the evolutionary history of crocodilians is published by Rio & Mannion (2021). [48] New fossil material of Deinosuchus, representing one of the earliest records of this genus in North American reported to date, is described from the Campanian Menefee Formation (New Mexico, United States) by Mohler ...
An early Campanian assemblage of anuran bones, suggestive of high local species richness of frogs, is described from the Aguja Formation (Texas, United States) by Wick (2021). [174] Fossil material of Late Cretaceous frogs, including fossils of calyptocephalellid frogs and the southernmost record of pipids (Kuruleufenia) worldwide reported to ...
Evidence of the impact of the interplay of abiotic and biotic processes on the evolution of pseudosuchians is presented by Payne et al. (2023). [13]A study on the biomechanical properties of the skull of Riojasuchus tenuisceps is published by Taborda, Von Baczko & Desojo (2023), who propose that R. tenuisceps could have had a wading habit, feeding on small-sizey prey caught from the shoreline.
