Helicoprion Shark in Cell Phone Game

My previous post showed an Edestus shark in the Jurassic World cell phone game. I encountered another fossil shark in the game called a Helicoprion. This shark-like creature was one odd fish in that its fossil consists of a spiral of teeth. It was eventually determined the spiral was located in the lower jaw. As the fish grew the smaller teeth were pushed into the center of the lower jaw. Read more at the Wikipedia entry:

The real shark existed from the Permian to Triassic (290-250 million years ago).

Edestus Shark in Video Game

The game developers of Jurassic World cell phone game have modeled an Edestus shark for the game. It showed up as one of the creatures to get past in the tournaments set for this weekend. It is interesting to see how the graphic designer modeled it's teeth in a single row.

The real shark is much older than the Jurassic Period. It dates to the upper Middle Pennsylvanian or Carboniferous Period (approximately 307 million years ago).

See this entry from 2015 about an actual Edestus fossil found in a Kentucky coal mine.
