Summary

This new discovery is WEIRD. Mirasaura (the 'marvellous lizard') has been described from the Triassic of France, and it has mad projections coming out of its back, far longer than its body. We take a look at what these projections were, and were not (i.e. not feathers), their implications for the evolution of integumentary structures, and our own historically bad haircuts. The paper is "Triassic diapsid shows early diversification of skin appendages in reptiles" by Stephan Spiekman and colleagues, published in Nature in July 2025. https://doi.org/10.1038/s41586-025-09167-9 Wide screen art: Gabriel Ugueto
