Some Quickie Drawings of Late Triassic Life

Hi everybody. As many of you already know, I occasionally volunteer at the Garvies Point Museum in Nassau County, New York. One day, I decided to hash out some drawings of Late Triassic creatures when I had a few moments of spare time, and I stuck them on the wall over the bulletin board. Recently, I went back to the museum for their annual Native American Feast, and to tell you the truth, I had completely forgotten about these pictures. I decided to take some photos of them while I was there. I’m hoping that the museum staff uses them for coloring activities with the children that visit the museum every week.

Two Triassic Pycnodont Fishes: Brembodus and Eomesodon

Here are color pencil drawings of two genera of prehistoric fish. Their fossils have been found in central Europe in rocks dating to the late Triassic Period. Both of these fish belong to a group called the pycnodonts, and it seems that they fed primarily upon mollusks and small crustaceans. Pycnodonts first appeared during the late Triassic Period, and became completely extinct during the Eocene Epoch of the Tertiary Period.

Brembodus

The first one is called Brembodus ridens. Among its features was a short spike on its back formed by extensions of the skull bones. This might have been meant to deter predators, like a modern-day triggerfish.

Eomesodon

The second fish is called Eomesodon liassicus. It looked remarkably similar to a modern-day tang or surgeonfish, except I’m not sure if the typical surgeonfish caudal blade (a sharp pointed piece of bone, located on both sides of the base of the tail, which could be extended if needed) has been found in association with specimens of this particular genus. As to the color, it’s pure guesswork on my part.

Hope you enjoy, and I look foward to any feedback.
