Summary:

- This article discusses the discovery of a prehistoric, water-dwelling creature that lived around 275 million years ago. This creature, known as Diploceraspis, had a unique and bizarre appearance, including sideways teeth and a twisted jaw.

- Diploceraspis was already considered a "living fossil" during its time, meaning it had features that were similar to much older species. This suggests that this creature had remained relatively unchanged for a very long period.

- The discovery of Diploceraspis provides valuable insights into the evolution of life on Earth, particularly the diversity of organisms that existed during the Permian period, which was a time of significant change and extinction in the planet's history.
