Possible Trilobite and Bivalve Fossils found by side of road in Sharon CT.

[cabes234]

Two days ago some workmen laid some stone by the side of a road near a pond in Sharon CT and I found two fossils one that appears to be the back of a Trilobite or a Chiton and another that looks to me like scallops or some other bivalve (I know that scallops and trilobites never existed at the same time). Does anyone have any ideas as to what these could be. Also I know this rock is not from where I found it, it was probably sourced from a local quarry so I would have to check with the highway department of Sharon to figure out where these come from.

You're correct that this is a trilobite pygidium (tail piece). The order Pectinida itself actually traces back to the Paleozoic. The bivalve (top left) looks like Aviculopecten or something similar. The other shells appear to be different brachiopods.

This is obviously imported stone.

The trilobite pygidium looks like a possible dalmantid.

 

The shells look like strophemenid brachiopods. Wait for some other opinions, though.

When you say that this is imported stone, how far away could it be imported from. Is it possible that the quarry this came from is within driving distance or is that a pipe dream?

Probably not too far, looks like it may be from New York.

I am back at the spot I saw the trilo right now and found some more detailed specimens. Will update when I get home but it does look like the trilobite is a Dalmantid I can see the tail better.

I think, Strophomenid brachiopods could be a good suggestion, as Tim said.

Definitely strophs.

I have returned and have second examples of the trilobite and scallop like thing (the first 2 images) I also have two new things one that looks like another mollusk of some kind though much larger and another fossil that I can’t make heads or tails of.

[Thomas.Dodson]

No molluscs in these latest pics. Another trilobite pygidium, an orthid(?) brachiopod, and a spiriferid brachiopod. Kind of hard to see what is going on in the last picture.

[Fossildude19]

It looks to be a lower Devonian fauna.

The third photo looks like the brachiopod Macropleura macropleura.

That's some cool stuff! Those trilobite parts are very nie and complete and the brachiopods are great too. I agree with @Fossildude19 with the Lower Devonian as well as the identification for the spiriferid brachiopod.

Could this stuff have come from the Helderberg group in NY? the fossils and time period seem to match, plus it's fairly close by.

The trilobite might be a match with Anchiopsis anchiops, or similar.

I don’t know where the stone was sourced, but I intend to do some poking around at the Sharon highway department to find out. If I learn anything I will tell those who are interested. 
 

Also here is one last type of shelled organism I found at this place.

[Misha]

Ooh! That one is awesome. That is definetley the strophomend brachiopod Leptaena rhomboidalis, very beautful with those folds on the shell surface.

[cabes234]

I am sorry for asking so many questions this is still very new to me. But I have one more fossil that looks like the shell of a snail but am still not sure what it is.

[Huntonia]

Wow some neat stuff on this thread! A bit hard to tell with these pictures but this latest one looks like a gastropod to me. I'm afraid I can't help with genus or species.

No need to be sorry, this is a place to ask questions. This one looks like the gastropod Platyceras.
