Ancient skin Scientists have been able to detect for the first time a clear "skin" pattern from a 50-million-year-old reptile, using non-invasive infrared and synchrotron technology. The findings are ...
In vertebrates, skin colour patterns emerge from nonlinear dynamical microscopic systems of cell interactions. Here we show that in ocellated lizards a quasi-hexagonal lattice of skin scales, rather ...
The Lower Permian Richards Spur locality is the most speciose Paleozoic continental vertebrate assemblage currently known, and a significant proportion of the tetrapod diversity found at the locality ...
Cornified scales of reptiles increased their capacity to live in terrestrial environments. The stratum corneum is very thin, with little keratin. Skin is used for gas exchange. Thick keratin layer ...
