Gorgeous Orthoconic Nautiloids (Toronto/Ordovician-Georgian bay formation))

Recommended Posts

Hello to all! Its been a very long time since I've been on here, but my recent trips around the creeks in Toronto, Canada (in the Etobicoke area) have yielded some of my largest and most defined finds of all time, here are some of the nicest Orthoconic Nautiloids I had found yet:

Probably the nicest one in my collection at this moment, found almost completely by fluke when I hit a rock with my pick and this bad boy showed up :)

These last couple would be way nicer, if only I could find a way to get it out of the rock matrix without completely destroying the specimen :/ ...

 

Anyways, it good to be back and hunting this summer after a somewhat stressful finals season. I also have wayyyyyy more stuff that I found such as some unusually large and defined bivalves and tentaculites (maybe?), but I might save those for another time as they definitely weren't as cool as these ones.

 

All were found along river rock deposits In the west side of Toronto (Etobicoke, Humber and Mimico creek) - Georgian Bay formation, excavated using rock pick and chisel.

I'd say that looks about right to me! Honestly, I don't know many of the Latin names, I just call them all orthoonic nautiloids and leave it at that haha

Nice ones! I'd like to see your bivalves and Tentaculites also.

Once you get a feel for the right kind of rock, then your pick hammer strikes wouldn't be so flukey any more, but rather deliberate.

You should get in touch with @Malcolmt in Mississauga. I think he might be willing to show you the ropes.

Very nice specimens! Congratulations. The nautiloids of the Georgia Bay Formation have always impressed me. Someday I'll have to get up there.

Thanks! Yes I still get awestruck every time I find a big intact Nautiloids, it just baffles me that there are all these amazing fossils right under our noses in the middle of the bustling city and all it takes is an afternoon, a hammer and some good eyes!

Okay good advice, thanks! I've started to get the hang of the right kind of rock to look for, but this one still caught me by surprise - definitely didn't think it was going to be that complete and split perfectly down the middle.

Okay I might follow this post up soon with some of the other nice stuff I've found since the end of exam season. Coming soon!

Hey Em - nice nautiloids! 

 

Re: your possible Tentaculites - it's probably Cornulites flexuosus since this species is most definitely found here in the Toronto area and I'm not sure if Tentaculites is.  And I'm sure we'd all love to have a look at it, regardless of what its scientific name is :popcorn:

@Wrangellian Here are some of the other bivalves in my collection that I haven't posted yet (the tentaculites are actually all crinoid segments woops):

 

A couple different Rafinesquina brachiopods:

Some Pholadomorpha pholadiformis casts:

Crinoid segments:

I don't know why I haven't posted the Rafinesquina brachiopods yet, I think thy are some of the prettiest and most defines fossils in my collection - although I only have a couple of them.

I have a lot of other shells with varying degree of quality, but almost all of them are Ambonychia and Pholadomorpha pholadiformis bivalvesThese are some of my nicer ones here.

 

Sorry it took a while, I totally forgot to get back to you about these:headscratch:- better late than never I suppose!

Ah, good. Some of those brachs are very nice - they retain some shell! If only you could find some bivalves like that.

The crinoid stems are quite nice too, and the orthocones.

Thats the actual shell hunh? cool!

 

Well the smaller Pholadomorpha pholadiformis on the left is actually a perfect split today, and both sides have that black surface. It seems that they don't ever retain the 'actual' shell...or maybe that is what the actual shell looks like?

Well I wouldn't bet that they are unaltered, original shell - they've probably been altered somewhat, especially after 400 million years, but I don't know. What I meant was there is some 'shell' as opposed to cavities left after the shell has been dissolved out, like your most of your bivalves seem to be.
