A mammal discovered near the top of a layer of flat bedded shale or slate in Tanzania. The fossil is about 40cm.

[Editor: Ok, we admit African fossil mammals are not our specialty. Is anyone familiar with fossil mammals that would like to contribute to the discussion? The collector would like to find out more about this find. Please leave a comment.]
Walking on the beach and my daughter was digging in the shore line and discovered it.

[Note: Nice find! looks to be half of a large Carcharodon megalodon shark tooth from the Miocene Period— Go back and dig for more!]
Found on a reef next to oyster and clams shells in the Mancos Shale. Believe the black material is "skin." First thought these were tail spikes from a dinosaur but this is shallow sea environment. Can you help me identify them?
Fossil Collector: Mark P.
Location: Mancos Shale
[Note: The Mancos Shale is an Upper Cretaceous formation of Utah and the Colorado Plateau. This find is something we we we could pick up and take a closer look at, but the general impression of the black areas reminds us of large fish bones and scales. The size of these are a bit daunting. For your dinosaur theory, it is not unusual to find terrestrial animal fossils in marine deposits because a watery environment is generally needed for them to become fossils. Terrestrial animals are washed into rivers, marshes and oceans all the time. As a famous example, the first dinosaur discovered in the United States is Hadrosaurus foulkii which was uncovered in a Cretaceous marine deposit in Haddenfield, New Jersey. Hopefully someone familiar with these fossils can leave a comment for us.]
Found along the sand beds of the Missouri River at Ponca State Park, Nebraska. The river was low enough to traverse most of the sand beds by foot.
Took the kids for a walk across the river and stumbled across this. Not sure it's even a fossil to be quite frank!

[Editor: That makes two of us, but it is a nice find. What do you think? Is this an ice age mammal or something more recent? Please leave a response.]
Can someone identify the animal that this tooth came from (its about 10cm long) and set in sandstone. I found this on the beach at lime regis about 6 years ago. I found this on a family holiday to Lime Regis and have always thought of it as a sharks tooth, but as I have got older I realise that it is not (the shape of the root is wrong) and it is quite large at roughly 10cm from tip to tip so now I am trying to find out exactly what it is. —Paige

[Editor: Very nice find! This appears to be a handsome mosasaur tooth. A mosasaur is a marine version of the modern monitor lizard some of which could achieve enormous size. The large root seems atypical for mosasaur teeth at this location so maybe collectors more familiar with Lyme Regis can leave a comment.]
