xerikaaax Posted July 12, 2020 Share Posted July 12, 2020 Found these fossils recently and was wondering what fossils they could be two weren't really sure even are fossils Link to comment Share on other sites More sharing options...
Ludwigia Posted July 12, 2020 Share Posted July 12, 2020 That last one looks like part of an orthocone nautiloid. Not sure about the first ones though. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

I agree, the item in the first picture might also be one that has been squished or damaged Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted July 12, 2020 Share Posted July 12, 2020 These were found in Jamaica? Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
ClearLake Posted July 12, 2020 Share Posted July 12, 2020 I’m pretty sure that’s Kingston, Ontario, Canada. But finding that in Jamaica would be way more unique. Link to comment Share on other sites More sharing options...
xerikaaax Posted July 12, 2020 Author Share Posted July 12, 2020 Found in Kawartha region in Ontario, Canada Link to comment Share on other sites More sharing options...
Kane Posted July 12, 2020 Share Posted July 12, 2020 The second specimen is an orthocone nautiloid as @Ludwigia said above, from an Ordovician exposure. It would be easier to make an identification if there was a scale of measurement. These are steinkerns. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Kane Posted July 12, 2020 Share Posted July 12, 2020 Do use a ruler. Almost no one outside of Canada knows what a loonie is. Our science relies on measurement (preferably metric). ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Kane Posted July 13, 2020 Share Posted July 13, 2020 Hey @Monica, I think we may have material that is, or is close to, Georgian Bay Fm here. What does our friend Hessin and his book say? I could venture a few guesses, but you are much more familiar with that neck of the woods than I am for non-trilobitic stuff! 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
FossilDAWG Posted July 13, 2020 Share Posted July 13, 2020 The nautiloid is a Gonioceras, likely Gonioceras anceps. The way the sutures bend backward at the periphery is diagnostic of the genus. Don 4 Link to comment Share on other sites More sharing options...
Monica Posted July 13, 2020 Share Posted July 13, 2020 FossilDAWG is definitely the expert! Here's what Hessin (2009) states: "Gonioceras is a strange cephalopod which had a wide, low, flattened shell like a flounder. Most paleontologists believe it was a bottom dwelling predator because of its shape. Internally, it is somewhat similar to Actinoceras but the segments of the siphuncle are greatly shortened lengthwise. The septa are very close together and curve forward from the siphuncle until they flare out towards the lateral edges of the shell. This cephalopod is fairly well represented by Gonioceras anceps in the Upper Gull River Formation." (p. 151) "The Upper Member is equivalent to the Moore Hill Formation of Okulitch (1939). His type section is the Moore Hill Roadcut about 3 km north of Coboconk. In this area the member is only about 1.2 m thick and consists of grey, greenish grey, and brownish grey semi-crystalline sublithographic and lithographic limestone in beds 15 to 75 cm thick. Eastward towards Marmora the member thickens to almost 4 m." (p. 18) I love nautiloids - nice find! 2 Link to comment Share on other sites More sharing options...
