Assessing ontogenetic maturity in extinct saurian reptiles
Morphology forms the most fundamental level of data in vertebrate palaeontology because it
is through interpretations of morphology that taxa are identified, creating the basis for broad …

Chthonic severance: dinosaur eggs of the Mesozoic, the significance of partially buried eggs and contact incubation precursors
JD Hogan, DJ Varricchio - Philosophical Transactions of …, 2023 - royalsocietypublishing.org
For most dinosaurs, clutches consisted of a single layer of spherical to sub-spherical, highly
porous eggs that were probably fully buried. Both eggs and clutch form change drastically …

Fossil biomolecules reveal an avian metabolism in the ancestral dinosaur
Birds and mammals independently evolved the highest metabolic rates among living
animals. Their metabolism generates heat that enables active thermoregulation, shaping the …

Phylogenetic and physiological signals in metazoan fossil biomolecules
Proteins, lipids, and sugars establish animal form and function. However, the preservation of
biological signals in fossil organic matter is poorly understood. Here, we used high …

[HTML][HTML] An exquisitely preserved in-ovo theropod dinosaur embryo sheds light on avian-like prehatching postures
Despite the discovery of many dinosaur eggs and nests over the past 100 years, articulated
in-ovo embryos are remarkably rare. Here we report an exceptionally preserved, articulated …

Pushing Raman spectroscopy over the edge: purported signatures of organic molecules in fossil animals are instrumental artefacts
Widespread preservation of fossilized biomolecules in many fossil animals has recently
been reported in six studies, based on Raman microspectroscopy. Here, we show that the …
