Kane Posted August 17, 2021 Share Posted August 17, 2021 Are you sure this is a Maclurites? The whorl side tends to be flat, and this image seems to show a bit of a higher spire. 2 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
New Members SK1993 Posted August 17, 2021 Author New Members Share Posted August 17, 2021 It may be another genus closely related to maclurites, thank you I am not completely sure if it is maclurites! Link to comment Share on other sites More sharing options...
FossilDAWG Posted August 17, 2021 Share Posted August 17, 2021 It would be best to see another view, such as directly from the side. However, as Kane says, Maclurites has no spire at all, and the "top" is completely flat. These snails rested "upside-down" on the sea floor, with the flat surface providing a stable base to keep them from flipping over. Unlike other snails they were sedentary, i.e. they sere stationary on the the sea floor, and they were often very large. I have one in my collection that is over 10 inches across!

Fossildude19 Posted August 17, 2021 Share Posted August 17, 2021 Definitely not Maclurites. Cropped, brightened, and enlarged.: This looks like an internal cast, so it may not be identifiable. Where was this found, and how did you arrive at Ordovician as an age? 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."

I found out that it's Ordovician from a loacal paleontologist, here are more photos: Link to comment Share on other sites More sharing options...
Fossildude19 Posted August 18, 2021 Share Posted August 18, 2021 There are a number of gastropods mentioned in This PDF, including some unidentified steinkerns, like yours. Knowing an ball park location, or even what Formation you were hunting would narrow down the possibilities.

New Members SK1993 Posted August 18, 2021 Author New Members Share Posted August 18, 2021 (edited) Found this around 10 miles north from Las Vegas, the new fossil is for comparison between the two specimens.
