Rattlesnake Creek Micro Fossils

Recommended Posts

DanKurek



G'day everyone!

 

Around a week ago, I received a package of micro matrix from Rattlesnake Creek (Aged late Miocene?), generously given to be by the amazing @GeschWhat. I have only gone through the matrix but was not disappointed. The micro matrix was packed full of shark, ray and fish material, as well as a couple of small bones. Here is some photos of my finds. I have attempted to ID some and left others. If you can ID some of my finds, it would greatly appreciated. :)

You made quick work of that, Daniel! I believe Rattlesnake Creek material can range between the Miocene and Pleistocene. For your records, this material was collected by @Sacha. I want to say the round crusher tooth is from a pycodont. :)

The shark tooth in the top left is a Physogaleus contortus and the rest are carcharhinids. Your ray teeth are Myliobatis and Aetobatis.

Nice specimens.

 

Shark Teeth.  The first tooth looks like a tiger (Galeocerdo).  The rest of the teeth look like Carcharhinus sp. although there could be a couple of Lemon shark teeth in there (Negaprion) especially the last tooth.

 

Ray Teeth.  The first four look like Aetobatis teeth from the lower dental plate.  Then Myliobatis or Rhinoptera medial teeth or Aetobatis teeth from the upper dental plate .

 

Agree with Lagodon teeth.

 

Agree with Rhynchobatus teeth.

 

Agree two of the three specimens are fish teeth.  The middle specimen looks more like a crab claw tip.

C. hastalis have nutrient pores but don't have nutrient grooves.
