Among living crocodylians, alligatoroids exhibit a wide range of body sizes and biogeographic distribution that spans tropical-to-subtropical climates. The fossil record alligatoroids, however, reveals even greater diversity, including multiple examples gigantism broader extends into polar latitudes. Osteohistological studies on extant show alligators caimans both seasonal growth, with roughly comparable growth rates. However, diverged from one another over 60 million years ago; the dearth...
Bone histology grants substantial insight into the growth and biology of fossil vertebrates. Many major non-avian dinosaurian clades have been extensively sampled for bone histologic data allowing reconstruction their as well assessment evolution changes along phylogenies. However, horned ceratopsians are poorly represented in paleohistologic studies. Further, ceratopsian taxa that examined unevenly phylogenetically with very basal forms highly derived making up majority studied taxa. In...
Abstract Fossils of embryonic and hatchling individuals can provide invaluable insight into the evolution prenatal morphologies, heterochronies, allometric trajectories within Archosauria but are exceptionally rare in Triassic fossil record, obscuring a critical aspect archosaurian biology during their evolutionary origins. Microvertebrate sampling at single bonebed Upper Chinle Formation Petrified Forest National Park has yielded diminutive archosauriform femora (PEFO 45274, PEFO 45199)...
