Found in Ocean City, MD after most recent nor’easter. Weighs about 4 lbs, about 8.5-9 inches by 7.5-8 inches. Any tips on what this is or what it might have belonged to are much appreciated!

Found a bunch of smaller rocks with what looked like a ton of fragments of shells embedded in them. These two were sticking out the top of a giant boulder (cap for boulder scale in third pic)

My grandma found it outside

Look at this flint stone that looks like a femur! Can anyone give me more information about this? I found it near Orléans, in Sandillon, France, on a railway track. It has a hollow cavity running perfectly through it. It's about 6 cm long and 2.5 cm thick. The hole in the middle is 0.6 cm in diameter.

Estaba en la terraza de un restaurante en Bretaña, Francia, cuando me fijé en el suelo, que era de grava, y encontré este pequeño fósil en una de las piedras. ¿Alguien podría decirme qué podría ser o qué antigüedad tiene? ¿Es algún tipo de esponja? El suelo donde lo encontré es ornamental, así que no proviene de allí, probablemente de alguna cantera de sílex cerca de la Bretaña francesa.

I know I have some coral pieces on the towel, but the one that looks like an ironing board has me curious especially and the ones that look like buttholes? Kentucky for reference, near rock-castle county

Stylemys Turtle Fossil. I just love the underside of this shell. I almost want to display it vertical so I can see that side more.

Happy to share always gorgeous fossils such thoses beauties that I used to digging many years ago . After a year I can be back with some beautiful fossils.
Also I put some of them as they are sliced and polished . This show how the structure outside /inside just amazing it show also that thoses are agatized fossils . Looking forward to seeing your comments and maybe your questions .
Have a great day

Hi! I’ve had this fossil for maybe 15 years now, I found it on the shores of a teeny tiny remote island off the coasts of Tasmania, my uncle took us over on his small boat and amongst all the shale I found this little dude. My assumption has always been that it’s potentially an ammonite? But I’ve recently been challenged that it may be fossilised poop haha. Was hoping someone with a better understanding could confirm for me :)

Last weekend, I was walking along the coast between Steart Marshes and Hinkley Point in Somerset when I spotted this unusual pebble on Steart Beach.

On one side, there appear to be faint markings resembling an ammonite or similar fossil.

When I turned it over, I noticed what, to my untrained eye, look remarkably like teeth - possibly a molar and two canines. They almost look drawn on, but they’re part of the stone’s natural markings.

I’m certainly no expert, so I’m curious what others think. My two theories are:

A. They’re simply natural patterns that happen to resemble teeth.

B. Could they be fossilised teeth from a creature that had an ammonite in its mouth?

I’m leaning towards A being more likely, but I’d love to hear from anyone with more knowledge!

Thanks in advance!

I am looking for marine reptiles or other interesting living things
