This partial skeleton of Mesosaurus tenuidens is from the early Permian of Brazil. The age of this fossil amounts to approx 280 million years. The stone was broken once, it measures about 30 x 18 x 3 cm. These fossils used to be available for purchase from time to time, but since the strict export ban that Brazil imposed a few years ago, no pieces have come onto the market. The reptile offered here is an exhibit from an old collection. Rare but affordable document piece!
