That was a terrible joke to claim as your own. Check this find out

Anyone want to take a crack at the first item, or is it a POR? The little black ‘teeth’ imbedded in it make me wonder… - Jon

Thank you, Digit, Shellseeker, Fin Lover, et.al. - Jon

Very interesting discussion! I don’t really have a grasp of how Bayesian methods work - despite sitting in on a few lectures Maybe I do? But if I understand correctly you can start to incorporate prior knowledge of how a system works into your calculations? I’ve used software to create radiocarbon age-depth models before and you can include prior knowledge/assumptions on how the sediments were deposited (e.g. constant vs pulses of sediment).

Indeed! Super worn and polished. If it is turtle it would likely be from the softshell turtle (Apalone sp.). You nailed it! It is "squished" phosphate. Cheers. -Ken

2024 Fossil hunting in Antwerp, Belgium
Shellseeker replied to dries85's topic in Fossil Hunting Trips
Thanks .. You are definitely right.. I was wanting a high res photo of just the Whale tooth for my local folder.. I am intrigued by rugose enamel..

I meant that none of them are from the ocean. Nevermind...a joke isn't funny if you have to explain it.

New to fossils/geology - excited to be here

Welcome from the Carboniferous of Illinois. Check at the local library under f for fossils and read all you find. After that it gets extremely site and species oriented and less inviting unless it's the exact area of you interest. However, that's where the true joy begins. -
Chunk o bone. Can't really ID it as anything since it DID come from ocean and concurrence seems to be not a fossil. Since it can't really be dated, any guess is just as likely as any other guess.

What are the dimensions of this specimen?

Believe you'd be wrong there. Cattle weren't native to North America until 1500s. Pigs came over at the same time. Wild boar weren't introduced until 1890. Etc... i

Pennsylvanian Cordaites principalis leaf and Cordaites borassifolius Stern bark

Looks like coalified layers that have peeled randomly. -
Your last photo is typically identified as turtle shell. I would need one of our "turtle guys" to identify the species. @digit @Plantguy

It's in the bottom right corner of the next to the last image.

Then deer, horse, cow and pig would be just as likely as your guess of human. Edit: we posted at the same time
-
Yes, yes of course. I was just saying that my guess is that more humans have been lost in the ocean especially around here where there are over 300 shipwrecks just off the coast of lower Delaware since 1600s. It's just fun investigating, I'm not pursuing DNA for a murder victim on Dateline

Shellseeker replied to dries85's topic in Fossil Hunting Trips
I love Whale... Can you show us a washed version of this tooth and, do you know which whale ? Thanks, Jack -
all rivers flow into the ocean, and then the ocean gives us back some of that detritus.

Cretaceous Fossil Shrimp (need help identifying)
Fossildude19 replied to Red October's topic in Fossil ID
Most shrimp from there are just listed as Carpopenaeus sp. or Carpopenaeus callirostris. -
It did come out of the ocean so....
