From the album: FOTM - Bone Valley Formation, Florida, USA
Upper Right P4 from a Black Bear -
Hi all, does anyone know why fossils from Cave bears usually are very lightly colored? The dentin and enamel in their teeth also look like they've hardly even been fossilized.

I'm interested in this Cave bear proximal phalange but I'm unsure if it's authentic or not, or if it is indeed U. spelaeus or another species of Ursus. Found in Austria.

I am looking to use a cave bear molar as the charm for a necklace; My thoughts were to insert a ring into the hollow of the root and attach it with epoxy glue. There is also a very small crack in the enamel, and I am looking to strengthen it all over. I would be grateful to hear any advice on this. Thanks

Pretty nice day yesterday Sunshine, but cool, especially if the clouds blocked the sun and the breeze picked up. I was glad to have a 5 mm wet suit. My find of the day is a nice Ursus m2. These are rare !!! especially for me. I have found exactly 4 in 12 years of hunting. At this size, a female or juvenile. It is nice being on the river. The effort in digging and sifting is "on automatic". I think mostly about fossils and the Peace River. Salt water is not all that common in the center of Florida around Fort Meade, going north. According to historical sea level data, the last time we have lots of salt water was 3-4 million years ago , and previous to that, around 12 MYAs. When I see a sea shell in my sieve, I always wonder WHEN did that shell contained its original inhabitant. Was it 3 million or 12 million or maybe earlier. At a minimum , I need a shell I do not recognize in our modern assemblage of Florida shells. Hopefully, I have some friends on TFF who can comment. @MikeR is definitely one of those... This fragment might be Turritella magnasulcus, from the late Pliocene of the Tamiami Fm So, is there enough of this shell to tell us what it is ? When was this shell being dropped?

From the album: Vertebrates (other than fish)
Cave Bear fang tooth (carnassial) 11cm long. It's from the so-called "Drachenhoehle" in Mixnitz, Styria, Austria. Cave bear fossils from the Late Pleistocene have been found there for a long time and were generally identified as Ursus spelaeus, but it was first established through a detailed study in 2004 that all of these fossils actually belong to the smaller newly identified species U.ingressus. I snapped this one up recently on a good deal from our favorite auction site.-
