This is a lot of fossilized bones recovered from Florida's Peace River (Bone Valley Formation). These are large pieces of bone that are broken and cannot be positively identified. Specimens such as these would be ideal for study, destructive analysis, carving/scrimshaw, or crafts/art.
The Bone Valley Formation contains fossilized bones from the Miocene, Pliocene, and Pleistocene periods (approx. 13,000 to several million years ago). The bones are mixed up and tumbled over time by the river and deposited into gravel bars where I find them. Large bones like these can only originate from megafauna such as mammoth, mastodon, whale, giant ground sloth, etc. Due to their incomplete condition, it is difficult to authoritatively identify them.
This lot contains several large pieces that weigh a total of 1021g (or a little over one kilogram, or 2.2 pounds).
Refer to the photo. You get all of the specimens shown. Your purchase will include an ID label with locality info.
Note - these will be shipped in a USPS Priority Medium Flat Rate box. A fixed shipping price of $15 is set for this lot. If you are overseas, you will be responsible for additional postage. If you are a US buyer and you order other items with this lot, I may be able to combine shipping and will refund any postage over the actual cost.
