Growth dynamics, skeletochronology, and histovariability of the theropod dinosaur Berthasaura leopoldinae

open access: yesThe Anatomical Record, EarlyView.
Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...
