Juvenile-adult habitat shift in permian fossil reptiles and amphibians.
Among extant large reptiles, juveniles often occupy different habitats from those of adults or subadults and thus avoid competition with and predation from the older animals; small juveniles often choose cryptic habitats because they are vulnerable to a wide variety of predators. Evidence from fossil humeri and femora of Early Permian reptiles collected from sediments of several distinct habita...
متن کاملNeural and endocranial anatomy of Triassic phytosaurian reptiles and convergence with fossil and modern crocodylians
Phytosaurs are a clade of large, carnivorous pseudosuchian archosaurs from the Late Triassic with a near cosmopolitan distribution. Their superficial resemblance to longirostrine (long-snouted) crocodylians, such as gharials, has often been used in the past to infer ecological and behavioural convergence between the two groups. Although more than thirty species of phytosaur are currently recogn...
متن کاملArthropod remains in the oral cavities of fossil reptiles support inference of early insectivory.
Inference of feeding preferences in fossil terrestrial vertebrates (tetrapods) has been drawn predominantly from craniodental morphology, and less so from fossil specimens preserving conclusive evidence of diet in the form of oral and/or gut contents. Recently, the pivotal role of insectivory in tetrapod evolution was emphasized by the identification of putative insectivores as the closest rela...

متن کاملWound Care in Reptiles
Reptiles are often presented to wildlife carers with various types and grades of wounds. Reptile wound healing rates are comparatively slower when compared to healing rates in mammals and birds. With appropriate wound management we hope to significantly reduce wound healing rates. How we manage a reptile‟s wounds will impact on the healing rate and thus influence the reptile‟s required time in ...
