Isotopic analysis of tooth enamel and bone phosphate (δ18O) allows paleobiologists to estimate body temperature. Data from sauropods and large theropods suggest body temperatures ranging from 36°C to 38°C. While this supports homeothermy (stable internal temperature), it remains debated whether this was achieved through high internal metabolism (endothermy) or sheer size (inertial homeothermy or gigantothermy).
The field evolves monthly. If you download a dinosaur paleobiology pdf from 2010, it will claim Spinosaurus was a wading heron. A PDF from 2024 will argue it was a fully aquatic, paddle-tailed pursuit predator. Here are three current debates you will find in recent PDFs: dinosaur paleobiology pdf
FEA allows researchers to convert CT scans of skulls into virtual 3D models. By applying simulated forces, we can visualize stress and strain. Studies on the T. rex skull reveal it was optimized for delivering powerful crushing bites rather than rapid slashing, supporting the hypothesis of osteophagy (bone-eating) in large tyrannosaurids.

The text shines when reconstructing behavior. It transitions away from speculative "Just-So Stories" to hypothesis-driven science. Evidence for ectothermy:
A modern paleobiology PDF is incomplete without addressing the digital revolution. This volume reviews the use of Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD).
While comprehensive, the text is not without minor flaws.
