Rockwood Posted May 30, 2021 Share Posted May 30, 2021 Could be just the way the beak of an inoceramid is exposed ? 1 Link to comment Share on other sites More sharing options...

JamieLynn Posted May 30, 2021 Share Posted May 30, 2021 If found in the Cretaceous part of Kansas- it looks similar to some of the Modiolus clams listed in the Houston Gem and Mineral Society book of Bivalves. www.fossil-quest.com Link to comment Share on other sites More sharing options...

Tim was spot on with trying to narrow down the age/options. Looks like it could be from Paleozoic aged source rock (Ps) (Pw) or (Pks--strip of the brightest blue along the Missouri river) or mapped as glacial drift--brown areas (Qgd). Not looking like any direct Mesozoic sources in the county...but that glacial element can certainly throw a wrench into determining age...Please tell us so we might narrow it down. Looks like this map was derived from the state map and not local survey info.. Thanks!

Myrmica Posted May 31, 2021 Share Posted May 31, 2021 Consider looking up the genus Pholadomya. This one has more obvious concentric lines than most but it has the appropriate shape 2 Link to comment Share on other sites More sharing options...
Plantguy Posted June 1, 2021 Share Posted June 1, 2021 Maybe its Wilkingia if this turns out to be Carboniferous aged stuff.. Found this thread where Missourian ID'd a similar looking Pennsylvanian bivalve. May need his thoughts/input if we get the age established. Not sure if additional views of the hinge/teeth will be needed... Done speculating for the moment... Regards, Chris 2 Link to comment Share on other sites More sharing options...

Plantguy Posted June 2, 2021 Share Posted June 2, 2021 @Missourian If this is Pennsylvanian aged do you think its possibly Wilkingia? Your thoughts please... I can see the Inoceramid similarity as Rockwood proposed and some of the other suggestions seem close as well. Does this example differ much from what you're finding in your neck of the woods? Thanks. Regards, Chris 1 Link to comment Share on other sites More sharing options...
Missourian Posted June 2, 2021 Share Posted June 2, 2021 Wilkingia yes. They have also been called Allorisma in older publications. 2 Context is critical. Link to comment Share on other sites More sharing options...
