DawnOfADream Posted April 2, 2020 Share Posted April 2, 2020 Hello everyone! Today I finally received a fish mortality plate (Pic 1) I had bid on a long time ago. Oddly though it turns out I had bid on multiple items and found this block of what appears to be fossil shells with coral structures at the bottom. After some googling I think it might be favosite? Any help is appreciated as I know little about fossil shells and corals. Unfortunately the providence is unknown, as no information was provided. Pic 1- Leptolepsis fish plate. Something appears to have been applied to the specimen and gone terribly wrong. If anyone has any advice to fix it please let me know! 2. Front of coral and shell slab 3. Back of slab (sorry for the blurriness) 4. Close up of the favosite (?) coral Link to comment Share on other sites More sharing options...
Misha Posted April 2, 2020 Share Posted April 2, 2020 Some of the impressions in the second picture appear to be that of horn corals or crinoids, it is hard to tell without more pictures. That piece also appears to have some spiriferid brachiopods, and the thing you are calling a favosites is not a coral but a fennestellid bryozoan of some sort. 6 Link to comment Share on other sites More sharing options...
doushantuo Posted April 2, 2020 Share Posted April 2, 2020 I think Misha is right on the brach and bryozoan count edit:to be utterly pedantic:I think you mean Leptolepis 3 Link to comment Share on other sites More sharing options...
DawnOfADream Posted April 2, 2020 Author Share Posted April 2, 2020 Thank you @Misha and @doushantuo! Here are some more pics. Hopefully they are helpful. Link to comment Share on other sites More sharing options...
TqB Posted April 2, 2020 Share Posted April 2, 2020 Fenestellid for sure, maybe Fenestella itself. 3 Tarquin Link to comment Share on other sites More sharing options...

If anyone has any advice to fix it please let me know! Leptolepis sprattiformis are often preserved with dendritic halos around them, but usually they are black. Those are mineral crystals that formed in the rock, by mineralized water seeping through cracks. I've never seen them in orange like that before, however. It could be a coating of some sort. Try to use a little acetone on a Q-tip in the corner, to see if it removes the orange substance at all. 10 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Kane Posted April 2, 2020 Share Posted April 2, 2020 I wonder if the orange might be on account of higher iron content that would precipitate an oxidized stain. 6 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Thank you! I tried the acetone at the top right corner and nothing came off. I looked around online and it appears that dendrites of similar colours are common in Solnhofen! Thanks for solving that, @Fossildude19 and @Kane, I really appreciate it! Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted April 2, 2020 Share Posted April 2, 2020 The piece with fenestellids and spiriferids looks like Mahantango Formation stuff to me. Very nice indeed. 3 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
