Recent histological studies suggest relatively rapid growth in dinosaurs. However, the timing
of reproductive maturity (RM) in dinosaurs is poorly known because unambiguous indicators …

The timing of sexual maturation in non-avian dinosaurs is not known. In extant squamates
and crocodilians it occurs in conjunction with the initial slowing of growth rates as adult size …

Medullary bone (MB) is a special endosteal tissue forming in the bones of female birds
during egg laying to serve as a labile calcium reservoir for building the hard eggshell …

If the dinosaurs Protoceratops grangeri and Hypselosaurus sp. grew at rates predicted for
their body size from extant reptiles, their expected ages at reproductive maturity would be …

Following an idea originally expressed by Björn Kurtén (1953), we here investigate the
notion that differences in the scaling of reproductive output could be responsible (at least in …

Despite nearly two centuries of investigation, a comprehensive understanding of dinosaur
biology has proven intractable. The recent development of means to study tissue-level …

Dinosaurs, like other tetrapods, grew more quickly just after hatching than later in life.
However, they did not grow like most other non-avian reptiles, which grow slowly and …

Hadrosaurs grew rapidly, and quantifying their growth is key to understanding life-history
interactions between predators and prey during the Late Cretaceous. In this study, we …

Did dinosaurs grow in a manner similar to extant reptiles, mammals or birds, or were they
unique? Are rapid avian growth rates an innovation unique to birds, or were they inherited …

We propose the hypothesis that in the long bones of large, rapidly growing animals,
secondary osteons may form to a greater degree in smaller bones than in larger ones for …
