Cretaceous Crocodyliforms from the Sahara
Diverse crocodyliforms have been discovered in recent years in Cretaceous rocks on southern landmasses formerly composing Gondwana. We report here on six species from the Sahara with an array ofExpand

Developmental plasticity and the origin of tetrapods
The origin of tetrapods from their fish antecedents, approximately 400 million years ago, was coupled with the origin of terrestrial locomotion and the evolution of supporting limbs. Polypterus is aExpand

Estimating evolution of temporal sequence changes: a practical approach to inferring ancestral developmental sequences and sequence heterochrony.
Developmental biology often yields data in a temporal context. Temporal data in phylogenetic systematics has important uses in the field of evolutionary developmental biology and, in general,Expand

Cranial Pneumatic Anatomy of Ornithomimus edmontonicus (Ornithomimidae: Theropoda)
ABSTRACT Modern archosaurs have extensive pneumatic diverticula originating from paranasal and tympanic sinuses. This complex anatomy is present in many fossil archosaurs, but few descriptions ofExpand

Permian tetrapods from the Sahara show climate-controlled endemism in Pangaea
New fossils from the Upper Permian Moradi Formation of northern Niger provide an insight into the faunas that inhabited low-latitude, xeric environments near the end of the Palaeozoic era (∼ 251Expand

A new neosuchian with Asian affinities from the Jurassic of northeastern Brazil
Phylogenetic relationships near the origin of extant crocodylians are weakly supported, and this lack of resolution makes for poor estimates of taxonomic and morphological diversity. Previously knownExpand
