Psephosaurus was a marine reptile that lived in the Middle Triassic seas, about 243 to 237 million years ago. It had a shell made of many small, pebble-like bones that protected its body. It swam in warm, shallow waters where it probably ate tiny floating creatures.1 1

Psephosaurus had a carapace, or shell, made of many small, irregular bone plates called osteoderms. The big plates were separated by smaller pentagonal or hexagonal ones.2

Its name means 'pebble lizard' because its shell looked like a bunch of pebbles.1

Psephosaurus belonged to a group called placodonts, which were marine reptiles that often had crushing teeth for eating shellfish. But Psephosaurus may have been a filter feeder instead.1 1

The first fossils of Psephosaurus were found in Germany in the Hoheneck limestone, which was once an ancient estuary or bay.1

Psephosaurus lived during the Middle Triassic, about 243 to 237 million years ago, in the Longobardian age.1 1

Only one species of Psephosaurus is known: Psephosaurus suevicus. It was named by German paleontologist Eberhard Fraas in 1896.1 1

Go fitlhelwa: Psephosaurus was named by German scientist Eberhard Fraas in 1896. The first fossils were found at Kugelberg near Ludwigsburg-Hoheneck in Germany, and they were pieces of a poorly preserved partial shell.1 2
Go sa ntse go ganetsanwa: Scientists are not sure exactly what Psephosaurus ate. The PBDB lists its diet as 'suspension feeder', but other placodonts usually crushed shellfish, so its feeding habits are still debated.1 1
