crabfossilsteve Posted August 30, 2020 Share Posted August 30, 2020 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. 7 Link to comment Share on other sites More sharing options...

JohnJ Posted August 30, 2020 Share Posted August 30, 2020 @crabfossilsteve Do you have photos of the halves prior to any prep (required)? The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
sharkdoctor Posted August 31, 2020 Share Posted August 31, 2020 Scientific name: Syllomus aegyptiacus Common name: Sea turtle Description of find: a large association of aegypticus carapace segments, vertebra and long bones.

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.

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!!!! 1 Link to comment Share on other sites More sharing options...
JohnJ Posted August 31, 2020 Share Posted August 31, 2020 @sharkdoctor We will allow more pre-prep photos (required) of the other jackets and a final of the smallest jacket.

crabfossilsteve Posted August 31, 2020 Share Posted August 31, 2020 John J 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. Link to comment Share on other sites More sharing options...
