Plesiochelys Explained

Plesiochelys ("near turtle") is a genus of late Jurassic European and Asian turtle. The type species is Plesiochelys etalloni.^[1]

Fossil records have discovered Plesiochelys bigleri and Plesiochelys etalloni from the Kimmeridge Clay of England and outside the Swiss and French Jura Mountains.^[2]

A recent study^[3] placed Plesiochelys as an Angolachelonia and outside Testudines.
