Whereas most living birds (including the ostrich) reach full size within a year, the internal bone structure of Confuciusornis shows that it grew more slowly. Like other small dinosaurs, Confuciusornis probably took several years to mature. This evidence suggests that birds apparently did not evolv...
It was about the size of a crow. The main difference between it and Archaeopteryx mainly in lacking a long, reptilian tail and its beak was toothless.
These tissue patterns, read straight, suggest lower growth rates than in the larger immediate relatives of Confuciusornis, the coelurosaurian dinosaurs, as well as in large extant birds, taxa that reached their large adult size relatively quickly. However, tissues of the inner cortex, as well ...

sanctus. Our analyses do not show any correlation between size distribution and the presence or absence of blade-like rectrices (tail feathers), thus implying, that if these feathers are sexual characters, they are not correlated with sexual size dimorphism. Our results also provide insights into...

Four plausible explanations were discussed to account for the resultant size classes: the existence of more than one species in the sample; sexual size dimorphism; two size classes corresponding to attritional death assemblages; and/or a particular growth pattern similar to that inferred for non-...

We found that histological age was not strictly correlated with body size. The variability in the histology of multiple bones from single skeletons suggests differences in the growth rate of the skeleton in response to allometry, functional demands, and pathology. We show that although fibrolamellar ...
