Stumped as the to ID of this odd looking Spiriferid, I looked it up in the most comprehensive resource available to me: Amadeus Grabau's "Geology and Paleontology of Eighteen Mile Creek" and it seems to match Spirifer("Mediospirifer") angustus (Page 213). The problem is this is not listed as a species that is found within the Widder formation. This is based on the 1958 publication "Checklist of Fossil Invertebrates Described from the Middle Devonian Rocks of the Thedford-Arkona Region of Southwestern Ontario by the University of Michigan.
So I may have found a new species that was not known from the Widder formation before now. Has anyone else seen a Brachiopod like this before?
Hey!

Very nice specimen Dave!
ReplyDeleteHey Squali, yours does look like the specimen I found. I'm hoping to get mine cleaned so I can view it in total 3-D glory.
ReplyDeleteGery, Thanks for the compliment!
