JohnBrewer Posted February 14, 2019 Share Posted February 14, 2019 A freebie to me. Common I’m sure, but what is it? From Parachute Creek I think. Yes, committed the cardinal sin, no scale. It’s around 8cm. @Fossildude19 2 John Map of UK fossil sites Link to comment Share on other sites More sharing options...
Fossildude19 Posted February 14, 2019 Share Posted February 14, 2019 Nice little Knightia eocaena. EDIT: PS - You might want to turn him over. He might be getting dizzy from being upside down. 6 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

JohnBrewer Posted February 14, 2019 Author Share Posted February 14, 2019 Thanks Tim. Yeah, I knew I had a 50% chance of getting it the right way up. I had actually photographed it the right way up but rotated it because it looked more natural! 2 John Map of UK fossil sites Link to comment Share on other sites More sharing options...
Fossildude19 Posted February 14, 2019 Share Posted February 14, 2019 With fish fossils showing the backbone attached to the skull, the vertebral column usually attaches to the top 1/3 - 1/2 or so of the skull. So if the vertebral column is in the upper 1//3- 1/2 of the body, that is the top. Or more simply, the verts are usually situated closer to the top of the fish than the bottom. Also, fin placement is helpful for figuring out orientation. The belly or bottom (ventral) side will have (if they are preserved well, that is, they aren't on yours) the pectoral fins, pelvic fins, and anal fin showing. Usually only one or two dorsal fins on the top. Sorry for the impromptu lesson. 10 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

RJB Posted February 14, 2019 Share Posted February 14, 2019 Hard to tell from the photo but there seems to be some paint work on the tail and the other fins? Not sure. but it looks very much like a Knightia from GRF? RB 1 Link to comment Share on other sites More sharing options...

I believe articulated fish fossils are not abundant there. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."
