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 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 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 کاملA Fossil Ant Colony : New
T h e fossil remains which will be described below are of exceptional interest for two reasons: ( I ) they are the first ant fossils to be reported from Africa south of the Sahara and (2) they comprise what appears to be a fragment of a colony preserved as a unit, thus constituting the first fossil insect colony ever recorded. From the sample we have been able to make measurements of the worker...
