ABSTRACT Understanding the pressure of emplacement of granitic intrusions is crucial to understanding the exhumation history of plutons and constraining the tectonic setting of magma emplacement. However, P–T and geochronological constraints from exhumed plutons are often characterized by large uncertainties, especially in shallow crustal settings with

Leidyosuchus canadensis and Stangerochampsa mccabei share endocranial features such as posterior projection of a neurovascular canal in the maxilla and a paratympanic sinus system most similar to those of small‐bodied and young extant crocodylians, suggesting that these pedomorphic features may reflect the ancestral crocodylian condition.

Postcranial anatomy of the Miocene hippopotamoids of Toros‐Menalla, Chad
We establish a framework for the identification of postcranial remains in hippopotamoids by describing and comparing for the first time two late Miocene hippopotamoids from Toros‐Menalla, Chad (Hexaprotodon garyam, an early hippopotamid, and Libycosaurus bahri, the last African anthracothere) with the common hippopotamus.

Simple rhamphotheca are externally homogeneous but internally are composed of several corneous layers with varying hardness. Areas under more mechanical stress such as the rostral portion and the tomia are significantly harder than other areas. Abstract Corneous sheaths on the jaws of beaked tetrapods, or rhamphothecae, are classified as simple or ...
