For the first time, researchers have analyzed fossilized soft tissue from a plesiosaur and discovered it had both scaly and smooth skin. The 183-million-year-old reptile's flippers featured scales while the rest of its body was smooth, likely providing both grip and reduced drag in the water.
ArticleBody:Scaly or smooth? That has long been one of paleontology’s enduring questions about the plesiosaur. While experts know details about its diet, size, and general habitat, the aquatic reptile’s skin characteristics have remained a mystery.
Due to the ongoing dangers of World War II, MH7 was subsequently reburied in a garden to protect it from accidental damage. Researchers exhumed the fossils yet again after the end of the war, but this time transported them into safekeeping at Urwelt-Museum Hauff in the nearby town of Holzmaden. In 2020, the Lund University paleontologists finally arranged to assemble and prepare the 183-million-year-old, 11.5-foot-long MH7 for its first-ever detailed tissue examination.
