MarielleK Posted January 9, 2018 Share Posted January 9, 2018 I have a few fish fossils here that are in a dark colored matrix. I do not know what species they are, nor how old. You can see scales preserved on them, which I think is pretty interesting. Any information about them would be very appreciated! Thank You!!

Fossildude19 Posted January 9, 2018 Share Posted January 9, 2018 Hello MarielleK, Any idea where they are from? Your first fish is a Semionotus sp. possibly from somewhere here in the north-east US. Your second one is a Semionotus, as well. It appears to be ventro-dorsally flattened. (On it's back, belly -up.) Both are very nice fossils! EDIT: Depending on where they come from, they could be Late Triassic (Rhaetian) to Early Jurassic (Hettangian) in age. (Between 204 million and 197 million years old.)

I think the guy who I got them from said they were found in Pennsylvania, but I could be wrong. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted January 9, 2018 Share Posted January 9, 2018 Lovely fossils! really detailed, fine fish. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Fossildude19 Posted January 9, 2018 Share Posted January 9, 2018 Hmm. Well I'm not real familiar with Pennsylvania, but I believe that the Newark Basin exposes the Lockatong formation in PA. So it's possible, but the preservation looks (to me) more like either Connecticut or New Jersey.

Wouldn’t be PA, lockatong, new Oxford, Gettysburg, hammer creek are the Newark super group formations and most are red (a few grey members but mostly red), none have I heard of such well preserved fish. Every now and then I have heard of complete fish but most of those probably end up in museums. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Fossildude19 Posted January 9, 2018 Share Posted January 9, 2018 But the Gwynedd shales have yielded complete fish in the past. I'm just unfamiliar with the preservation from those black shales.

Fossildude19 Posted January 9, 2018 Share Posted January 9, 2018 Just now, WhodamanHD said: To be honest I’ve never heard of that formation, so I can’t say anything there. It is a member of the Lockatong formation - but that is from an older paper, and may have been changed in the 80-100 years since. But I agree - they are more likely to be from NJ or CT.

With the sluggish pace of research into the geology of this areas, wouldn’t be surprised if it hasn’t. Good to know, have to research it more, Thanks for telling me about it “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
