Bone histology and growth in Stenaulorhynchus stockleyi (Archosauromorpha: Rhynchosauria) from the Middle Triassic of the Ruhuhu Basin of Tanzania

The bone histology of non-archosauriform archosauromorphs is understudied but is important for tracing the evolution of growth in archosaurs and their closest relatives. Here, we describe the femoral and tibial histology of a single individual of Stenaulorhynchus stockleyi, a Middle Triassic rhynchosaur from Tanzania. Both elements are composed largely of moderately vascularized parallel-fibered bone tissue, which becomes avascular and more...
