SawTooth Posted May 18, 2022 Share Posted May 18, 2022 I found this fossil a few years ago (since coronavirus started) in south Louisiana. I found another fossil tooth, likely mammal, that conveniently disappeared as soon as I got my forum account. It appears to be an Isapod like creature, any help? Sorry the picture quality is not great. Link to post Share on other sites
Rockwood Posted May 18, 2022 Share Posted May 18, 2022 I'm pretty sure that's a piece of coral pretending to be an isopod. 1 1 Link to post Share on other sites

Rockwood Posted May 18, 2022 Share Posted May 18, 2022 The transverse lines that appear to converge. They look like septa. 1 Link to post Share on other sites
C.P. Sheridan Posted May 19, 2022 Share Posted May 19, 2022 Could this be a redeposited fossil from an earlier era cast into Louisiana from the Mississippi River flood plain? I only suggest this because here in NJ the geology of SJ below the Cretaceous belt is mostly unconsolidated Quaternary sands and gravels. Here can be found silicified corals in chert gravels, along with brachiopod impressions of Paleozoic age that originated in a shallow sea before the original Appalachians. Older fossils can sometimes be reworked into younger strata. Thank God it isn't a two way street. Link to post Share on other sites

Lone Hunter Posted May 19, 2022 Share Posted May 19, 2022 It reminds me of praying mantis egg case, but this looks like there's something inside and what are the drippy leg looking things underneath? Looks like a grub worm of sorts more than coral Link to post Share on other sites
Bringing Fossils to Life Posted May 19, 2022 Share Posted May 19, 2022 I agree with the coral ID... If you took it off the rock you would likely be able to see for sure. Link to post Share on other sites

It's the inside that needs to be explained. The drippy structures look like the result of recrystallization and weathering to me. Neither would seem likely in the preservation of a case.

SawTooth Posted May 19, 2022 Author Share Posted May 19, 2022 So are you thinking I should remove the fossil from the rock? Link to post Share on other sites
