Summary This is a caudal vertebrae (tail bone) from an ancient cetacean. The animal was a juvenile, since the epiphysis is missing. Fossil is probably between 5-7 million years old. Found along the banks of the Siret river in Botosani county, Romania, by Gavriliuc Emanuel, Radiology Imaging Specialist with Spitaful Hospital in Botosani. Credit to Gavriliuc Emanuel (Thingiverse ID emi83ro) who provided the CT scan. The fossil is approx 1 inch in length, would best be printed at 200% resolution or with a SLA printer.
