August 2020 - Finds of the Month Entries


digit

Recommended Posts

Date of Discovery   7-20-2018

Scientific and/or Common Name - Lamniform Shark Vertebrae

Geologic Age or Geologic Formation -Paleogene   Eocene Late / Oligocene - Pittsburg Bluff Creek Formation   Mya : 33.9 - 55.8

State, Province, or Region Found - North Western Oregon

 

This is my first entry to the fossil of the month.  The entry is a set of two shark vertebrae in different orientations in a calcareous concretion.  The specimen was found (7/20/3018) and cracked in two halves reflecting a mirror image of both halves.  The specimen was kept like that until August 2020 when I decided to prep one half of the concretion and keep the other half as found.  I finished the prep work on August 27, 2020.  I used air scribes, air abrasive and a lot of grinding.  It took quite a bit of time to do this preparation, but was quite happy with the way it turned out.

Preparation: completed in August by Mike Ellwood (Calvert Marine Museum).

 

NOTES: The turtle bones were found in a shallow waterway in 10 feet of water. The specimen was recovered in 10" of visibility. The overall association is comprised of three distinct chunks of matrix that were each given an individual jacket. Before and after photos are provided for all three jackets (chunks), though the before photos vary in type and quality due to adverse field conditions.

NOTES: The turtle bones were found in a shallow waterway in 10 feet of water. The specimen was recovered in 10" of visibility. The overall association is comprised of three distinct chunks of matrix. Since this entry is limited to four photos, the first photo is a before photo taken in the field. The last three photos are of the largest chunks after significant preparation. I have not received a photo of the last (and smallest jacket) jacket after prep.

 

 

I saw that... GREAT find!!!!

We will allow more pre-prep photos (required) of the other jackets and a final of the smallest jacket.

Procyon lotor - Raccoon molar

Whilst sorting through Peace River micro matrix I discovered this unusual mammal tooth.

I have not seen anything like it before in the years I have been searching this matrix.

Thanks, @JohnJ! I've updated. Happy to edit more if I am still not in compliance.

As indicated above both halves of the concretion were identical to the first picture.  If required to have pics of both halves before prep then I do not have a pic of the other half before beginning prep.
