Plastic Development in Plateosaurus: Fast, but Environmentally-Dictated
In tomorrow's _Science_, yet more prosauropod goodness:
Sander, P. M. & N. Klein. 2005. Developmental plasticity in the
life history of a prosauropod dinosaur. _Science_
"Long-bone histology indicates that the most common early
dinosaur, the prosauropod *Plateosaurus engelhardti* from the
Upper Triassic of Central Europe, had variable life histories.
Although *Plateosaurus* grew at the fast rates typical for
dinosaurs, as indicated by fibrolamellar bone, qualitative
(growth stop) and quantitative (growth-mark counts) features of
its histology are poorly correlated with body size. Individual
life histories of *P. engelhardti* were influenced by
environmental factors, as in modern ectothermic reptiles, but
not in mammals, birds, or other dinosaurs."
