Welcome to the Forum. :) 

 

What's the size of the item pictured?

Were there any other fossils found?

Regards,

it is over a foot long

one end goes to the edge of the block of limestone

so it may have been even longer

i will have to go back down there to look for associated fossils

From the tapering and size of the item, I'd say it is probably an imprint from an orthocone cephalopod.

cool

there were a couple more imprints on the rock when i went back down to check it out

do you think there could be intact ones in the rock?

 

 

It's possible that there are intact specimens, but getting them out would be a nightmare.

It looks like a nice exposure of crinoidal limestone. 

It's packed full of fossils,...crinoid stems, sometimes weathered through, and pieces -  columnals, and lumen casts.

Bryozoans, colonial corals, bivalve shells, and  cephalopods are present as well.

I posted some examples here, for continuity and for those who do not wish to leave the forum to view the pictures.

Neat area, ... but I would keep the collecting to photos. Much to difficult to remove decent specimens from this type of limestone, due to hardness and cross-bedding.

is that a trilobite partial?

The fossils in the first pic are rugose corals. The second one actually does look like part of the pygidium of a trilobite. I could very well imagine that the rocks you have found were transported to the beach from elsewhere, where paleozoic rocks are present, since the insitu sediments at the bluffs are very young.

Hi subsonicdrone from a fellow Ontarian!

 

Welcome to TFF!

 

How big are your specimens?  That may help with identification - often people will place a ruler in the photo so the size of the objects can be known.

 

I think I maybe see some bryozoans (middle rock of first picture, rock on the right of fifth picture), orthoconic nautiloids (rocks on the right in the second and third pictures), as well as lots of corals (rocks on the left in the second and third pictures, second rock from the left - the one that's kind of orange in colour - in the fourth picture).

 

Hopefully someone else will be able to come along and help out...

edit: i just looked up bryozoans and i have found some of them on georgian bay a few years back

Wow - what a lot of solitary rugose corals you've got there!!!  So far I've only found one at the location where I look for fossils...I think I need to venture out a bit further afield this summer...

 

Thanks for sharing!

That looks like some rocks I've found around here in Etobicoke Creek - can you see tiny holes in the grey-white structures?  If so, then I think you have a branching bryozoan of some sort - the tiny holes are where the little colonial zooids once lived.

 

Thanks for sharing!
