AI Thread Summary
The discussion revolves around unidentified geological formations photographed in Toronto, Canada. Participants speculate on the nature of the formations, suggesting they could be nautiloids or crinoid stalks, with some mentioning the possibility of ammonites due to a tube-like structure observed. The geological context is highlighted, noting that while ammonites are typically found in Devonian layers, the area in question is primarily Cambrian Shield, making crinoids a more likely identification. There is also curiosity about the internal structure of the formations, with suggestions that they might be crystalline or coral-like. Overall, the conversation emphasizes the need for further context regarding the location of the finds to make a more accurate identification.

Hi everyone,

These pictures were taken by a friend of mine in Toronto, Cananda, and he doesn't know what it is.
Any ideas?

Would be my guess too. Some of those crevices go really deep though hmm that might be the inside of the shells. Thats pretty cool :smile:

Now why would you go post that here? Now we have to kill everyone that reads that message...

Ok everyone, if you read Daves message just leave a message with your address and the time-police shall be over shortly.
 
If you see a "roll of dimes", it is very likely a bunch of crinoid stalks.
But it looks like there's a tube running down the centre, which suggests perhaps Ammonite.

Where did he find hem?

Ammonites are primarily Devonian, and this area is largely Cambrian Shield so, if he found them near Toronto, more likely they're Crinoids.
 
I wonder if they are crystal on the inside, they may be a type of coral.
