Missourian Posted June 28, 2014 Share Posted June 28, 2014 These are all Ameura missouriensis. For some reason the usually-more-common Ditomopyge is very rare here.... Three views of three enrolled bugs. The largest is from the Westerville Limestone. The other two are from the Winterset Limestone: Context is critical.

Missourian Posted June 28, 2014 Author Share Posted June 28, 2014 Flat Ameura. Probably Winterset Limestone: Context is critical. Link to comment Share on other sites More sharing options...
Missourian Posted June 28, 2014 Author Share Posted June 28, 2014 Complete? Westerville Limestone: Almost complete. Westerville limestone again: Context is critical. Link to comment Share on other sites More sharing options...
Missourian Posted June 28, 2014 Author Share Posted June 28, 2014 I wish this excellent large cephalon had the rest of the bug with it. Winterset Limestone: Context is critical. Link to comment Share on other sites More sharing options...
Wrangellian Posted June 28, 2014 Share Posted June 28, 2014 Very nice! I like that last one even tho it is just the cephalon. Link to comment Share on other sites More sharing options...
Bullsnake Posted June 28, 2014 Share Posted June 28, 2014 Guess I'll have to look harder! Noting that your specimens are Westerville and Winterset (and knowing your fondness for Winterset), was there something about the environment or conditions when these strata were laid down that makes the preservation better, especially for more complete/intact specimens?

Noting that your specimens are Westerville and Winterset (and knowing your fondness for Winterset), was there something about the environment or conditions when these strata were laid down that makes the preservation better, especially for more complete/intact specimens? They are from either the oolitic/bioclastic shoals in the Winterset or Westerville or the bluish beds in the upper Winterset below the oolite. I'm still trying to sort out the environmental/depositional conditions, as you can imagine.... Context is critical. Link to comment Share on other sites More sharing options...
Missourian Posted June 28, 2014 Author Share Posted June 28, 2014 And yes, I am fond of the Winterset for its fossils as well as its lithological diversity, paleoecological and depositional complexity, beauty, etc. Context is critical. Link to comment Share on other sites More sharing options...

Missourian Posted June 28, 2014 Author Share Posted June 28, 2014 Very nice! I like that last one even tho it is just the cephalon. That popped out with a single whack of the hammer. I held my breath for a moment.... Context is critical. Link to comment Share on other sites More sharing options...

Rob Russell Posted June 29, 2014 Share Posted June 29, 2014 Nice trilo's! Are these recent finds? Or a compilation from the years gone by? Either way, congrats on your beautiful collection.

Missourian Posted June 30, 2014 Author Share Posted June 30, 2014 Thanks everyone for the comments. Nice trilo's! Are these recent finds? Or a compilation from the years gone by? Either way, congrats on your beautiful collection. All were found 20+ years ago. Some I found myself. Others were acquired from a friend/fellow hunter. Context is critical.

Missourian Posted June 30, 2014 Author Share Posted June 30, 2014 (edited) I have a few more Ameura pics floating around on the forum. I'll gather them here....
