A study evaluating the impact of different sampling effects on calculations of mean von Ebner line increment width (the measure of dentin thickness divided by the mean width between von Ebner lines), tooth formation times and replacement rates in fossil archosaurs, based on data from extant American alligator, is published by Kosch & Zanno (2020).

Sterling Nesbitt (born March 25, 1982, in Mesa, Arizona) is an American paleontologist best known for his work on the origin and early evolutionary patterns of archosaurs. He is currently an associate professor at Virginia Tech in the Department of Geosciences. [1]
This article records new taxa of every kind of fossil archosaur that are scheduled to be described during 2024, as well as other significant discoveries and events related to the paleontology of archosaurs that will be published in 2024.

A 2020 study of range of motion in the hindlimbs of Euparkeria found conflicting evidence for its posture. The structure of the femur (thigh bone) and hip socket suggest that the legs were capable of a very wide range of motion, ranging from a nearly vertical stance to a thigh which projects forwards, backwards, or outwards at a nearly ...
A new analysis of three-toed fossil footprints that date back more than 210 million years reveals that they were created by bipedal reptiles with feet like a bird’s.
Description of the fossil material of birds from the Magdalenian of El Juyo, Spain is published by Rufà et al. (2022). [356] Description of the fossil material of birds from the Dieu and Maxa I Caves in Vietnam is published by Boev (2022). [357] A catalogue of fossil and subfossil birds from Cuba is published by Suárez (2022). [358]
A study estimating moment arms for major pelvic limb muscles in extant and fossil archosaurs, aiming to investigate the idea that bird-line archosaurs switched from hip-based to knee-based locomotion between Archosauria (especially Neotheropoda) and Aves, is published by Allen, Kilbourne & Hutchinson (2021).
