Can Turtle Scales Unlock the Mystery of Dinosaur Skin?

Rapid Summary

• Turtles have existed as the Triassic Period over 200 million years ago.
• A new study published in iScience investigates the evolution of turtles’ scales and their link to dinosaur ancestors and living relatives like crocodiles and birds.
• While most vertebrates grow scales through genetic processes involving placodes,crocodiles rely on mechanical skin folding. Turtles are unique as they utilize both mechanisms: placodes on the side of their heads and mechanical skin folding for scales on the top.
• Observations using 3D light-sheet microscopy and computer modeling revealed irregular and asymmetrical patterns in turtle head scales due to mechanical folding differences between individuals, even within a single turtle’s anatomy.
• Research suggests this dual method existed in a shared ancestor of turtles,crocodiles,and birds-likely predating modern species and tracing back to dinosaurs.
• Insights from this study may pave the way for advancements in architecture, tissue regeneration, and material design by mimicking these natural processes.
