Osteoderms are mineralised structures consisting mainly of calcium phosphate and
collagen. They form directly within the skin, with or without physical contact with the skeleton …

Examining the geological past of our planet allows us to study periods of severe climatic and
biological crises and recoveries, biotic and abiotic ecosystem fluctuations, and faunal and …

Bone ornamentation, that is, hollow (pits and grooves) or protruding (ridges) repetitive reliefs
on the surface of dermal bones, is a frequent, though poorly studied and understood, feature …

Sculpture of dermal bones and their vascularization in basal tetrapods are closely
connected. Ontogenetic data suggest that the large vessels that coursed to the superficial …

Osteoderms, bone plates in the skin, are widely but discontinuously distributed across the
phylogeny of tetrapods. This and their pronounced morphological disparity has inspired …

One of the most striking features documented in aetosaurs is the presence of an extensive
bony armour composed of several osteoderms. Here, we analyse the bone microstructure of …

The skull and postcranium of the Late Triassic plagiosaurid temnospondyl Plagiosaurus
depressus from Halberstadt (Germany) are redescribed in detail. Plagiosaurus possesses …

Ornithosuchidae is a group of terrestrial quadrupedal pseudosuchian archosaurs from the
Late Triassic of South America and Europe. Riojasuchus tenuisceps is arguably one of the …

Abstract The Posidonienschiefer Formation of southern Germany has yielded an array of
incredible fossil vertebrates. One of the best represented clades therein is Teleosauroidea, a …

Bone ornamentation, in the form of rounded pits framed by a network of ridges, is a frequent
feature among a great diversity of gnathostome taxa. However, the basic osteogenic …
