Osteohistological data are commonly used to study the life history of extant and extinct
tetrapods. While recent advances have permitted detailed reconstructions of growth …

In the mid-19th century, the discovery that bone microstructure in fossils could be preserved
with fidelity provided a new avenue for understanding the evolution, function, and …

This paper is aimed at constraining the phylogenetic frame of the acquisition of endothermy
by Archosauromorpha. We analyzed the bone histology of Azendohsaurus laaroussii …

This paper is the first of a three-part series that investigates the architecture of cancellous
('spongy') bone in the main hindlimb bones of theropod dinosaurs, and uses cancellous …

Bones in the fossil record sometimes exhibit unusual structures that can be attributed to
pathologies, taphonomic alterations, or morphological variation. The goal of this work is to …

Studies on pathological fossil bones have allowed improving the knowledge of physiology
and ecology, and consequently the life history of extinct organisms. Among extinct …

Bone microstructure has long been known as a powerful tool to investigate lifestyle-related
biomechanical constraints, and many studies have focused on identifying such constraints in …

Other than repaired fractures, osteoarthritis, and periosteal reaction, the vertebrate fossil
record has limited evidence of non-osseous diseases. This difficulty in paleontological …

Abstract High-latitude (ie,“polar”) Mesozoic fauna endured months of twilight and relatively
low mean annual temperatures. Yet non-avian dinosaurs flourished in this taxing …

The histology of sauropod long bones often appears uniform and conservative along their
evolutionary tree. One of the main aspects of their bone histology is to exhibit a fibrolamellar …
