Pterosaur Egg More Reptilian Than Bird-Like (4 of 4)

Caption

This image shows sex-related features of Darwinopterus. The male (right) has a large head crest, but this is absent in the female (left). The coloring of the animals is very uncertain, but the dramatic differences in crest structure are shown by the new fossil evidence reported in a study by Lu et al. This image relates to an article that appeared in the Jan. 21, 2011, issue of Science, published by AAAS. The study, by Dr. Junchang Lü of the Chinese Academy of Geological Sciences in Beijing, China, and colleagues was titled, "An Egg-Adult Association, Gender, and Reproduction in Pterosaurs."
