deutscheben Posted May 29, 2019 Share Posted May 29, 2019 I posted this find in my trip report thread http://www.thefossilforum.com/index.php?/topic/95184-51319-oglesby-il-roadcut-pennsylvanian-shark-bits-brachiopods-and-more/ but I thought I would put it here too to get some more eyes on it. This piece is from the Pennsylvanian LaSalle Limestone member of the Bond Formation, collected on 5/13 and prepped some over the weekend. At first I thought it was the root of a shark tooth, but as I prepped and revealed the multiple "teeth" on top and the ratio of root to teeth it did not match up. That makes me think it is possibly a part of a jaw with teeth in it, but I have never found anything like that at this site before, nor have I seen any reported from this formation. Any ideas? The scale below is in CM. 4 Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 29, 2019 Share Posted May 29, 2019 What a cool looking find! Looks like a fish premaxilla to me. 5 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."
