Description
A partially preserved medial gastralium from an indeterminate Triassic reptile. Medial gastralium is a V-shaped dermal bone resembling a rib and forming part of the gastral basket – a cage or basket-like structure protecting the organs ventrally.
A bone of this type yields virtually no information regarding the animal’s taxonomic classification. Besides the fact that it was a reptile, we can guess that it was a marine reptile, perhaps Nothosurus or Cymatosaurus, but these are just speculations based on the frequency of occurrence.
