Sphenosaurus is a fascinating prehistoric reptile that lived during the Late Permian period around 252 million years ago.
It is part of a group called procolophonids, which are ancient reptiles.
Sphenosaurus was discovered in Germany and is not very well-known, so there is still much to learn about it.
Initially, it was named Palaeosaurus sternbergii by a scientist named Leopold Joseph Fitzinger in 1840.
However, the name Palaeosaurus was already used for other reptiles, which led to confusion.
In 1847, another scientist named Hermann von Meyer suggested a new name for this reptile, calling it Sphenosaurus.
The species name for Sphenosaurus is Sphenosaurus sternbergii.
This change helped clear up the naming issue and allowed scientists to better study this unique dinosaur.
Even though Sphenosaurus is not well understood today, it represents an interesting part of our planet’s ancient history.
