Osteohistological signal from the smallest known phytosaur femur reveals slow growth and new insights into the evolution of growth in Archosauria

open access: yesJournal of Anatomy, Volume 247, Issue 3-4, Page 556-575, September/October 2025.
The paucity of small, skeletally immature individuals representing the earliest ontogenetic stages of extinct archosaurs complicates our understanding of the growth dynamics within and between species. The opportune finding of the smallest phytosaur femora reveals slow growth, a surprising signal considering that larger phytosaurs in North America have
