Great information and Thank you for taking the time to investigate! It always fun to learn something new about a fossil. The museum is welcome to have this fossil for its collection.
Thank you for the information. I did not see a another ridge running perpendicular to the larger one. I did see very faint circular micropilar scars on one side and tried to photograph them (added text to photo to indicate what side they were observed). The other side of the seed is slightly eroded – unable to determine there are any micropilar scars.
Dr. MacFadden, Thank you for your help and providing the additional research information on the sesamoids bones – I will look on-line for more information like you pointed out -Joe.
