MoRockHunter Posted May 17, 2021 Share Posted May 17, 2021 I found this stuck to a rock covered in fossilized snails that looked similar to this, anyway I don't know what it was or is and figured somebody could help me understand this small mystery to me lol. Found in SW MO it is about an inch long and is hollow until about 3/4 of the way back toward the closed end. Link to comment Share on other sites More sharing options...
Thomas.Dodson Posted May 17, 2021 Share Posted May 17, 2021 This is a case from a larval caddisfly. LINK They're known to make cases out of various materials. Family Limnephillidae would be my guess without seeing the actual bug. 4 4 Link to comment Share on other sites More sharing options...
Thomas.Dodson Posted May 17, 2021 Share Posted May 17, 2021 Re-reading your post I see you mentioned fossil snails similar to this stuck to the rock. Are you sure those are not actually cases of the snail-case caddisflies, Helicopsychidae? LINK 3 Link to comment Share on other sites More sharing options...
FossilDAWG Posted May 17, 2021 Share Posted May 17, 2021 Just to be clear, the caddisfly cases are modern not fossil. Don 1 Link to comment Share on other sites More sharing options...

LINK Probably are, I don't know anything about them except that they look like snails and when I look at them magnified yeah they look like this tube does just a lot smaller.
