Marine reptile - Fossil skeleton - Barasaurus sp. - 21 cm - 9 cm

Positive and negative barasaurus of good quality.

Almost 300 million years old with a particularly beautiful light skeletal color and with gastroliet.
In fossil theropods (a group of dinosaurs related to birds), many gastroliths are found. Swimming reptiles, such as plesiosaurs, likely used the stones as ballast to help them balance in the water.
