AMNH Tour the Hall of Vertebrate Origins Video

 

Today, I found a great video series being created by the American Museum of Natural History (AMNH) in New York city. During the Covid epidemic, the museum is publishing videos every Friday at 1 PM EST as live stream. The last video was presented by fossil fish researcher Allison Bronson. She does a great job narrating a video tour of the Hall of Vertebrate Origins at the museum. I was there in July of 2018 and I wished I had watched a video like this before my visit. After watching the video, I missed taking pictures of at least two special specimens she highlighted. Have to go back now :)

I am weak on my understanding of fossil fish and vertebrates in general as we do not find a lot of those fossils in the Louisville area. When I was in this museum section, the Devonian shark Cladoselache caught my attention (see posting here, to know why):

https://louisvillefossils.blogspot.com/2010/07/cladoselache-shark-fossil.html

After seeing her talk about the shark at the 7:20 mark, I realize I am pronouncing its name wrong.

It was amusing at the 22:05 mark in the video, Allison talks about the happy tortoise which is one of the most photographed specimens in the museum. As it turns out, I blogged about the Geochelone atlas specimen in December 2018, so count me in that large group of photographers!

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: https://en.wikipedia.org/wiki/Helicoprion

Image of Helicoprion bessonovi from J. Walther old book in public domain - source Wikipedia https://en.wikipedia.org/wiki/Helicoprion#/media/File:Helicoprion_Bessonovi2.jpg 

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. http://louisvillefossils.blogspot.com/2015/01/newly-found-edestus-shark-fossil.html
