Samthefossilman Posted May 13, 2023 Share Posted May 13, 2023 Hi all I am looking at some fossils online but the seller doesnt have much information about them. I recognise one as an ammonite but unsure what species. I do not know anything about the bottom one. If anyone could help that would be greatly appreciated Cheers Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 13, 2023 Share Posted May 13, 2023 Any idea where they were found? The fish looks like a Leptolepides sprattiformis from Solnhofen. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Ludwigia Posted May 13, 2023 Share Posted May 13, 2023 There are not enough diagnostic features on the ammonite to determine even the genus, particularly when the stratigraphy and location are failing.

Samthefossilman Posted May 13, 2023 Author Share Posted May 13, 2023 (edited) Does anyone know what the yellow and then black lines on the back of the fish fossil are? Edit: Never mind did some looking appears to be Dendrite Edited May 13, 2023 by Samthefossilman Found answer 1 Link to comment Share on other sites More sharing options...
oilshale Posted May 13, 2023 Share Posted May 13, 2023 The ammonite could be from the Treuchtlingen Formation (Upper Jurassic, Kimmeridgian). The limestone is mined in the region of Treuchtlingen in the Altmühltal and processed to window sills, stairs and tiles. In this limestone very often fossils are found, such as ammonites and belemnites, which are sold cut and polished, often with the (false) designation of origin Solnhofen. See for example https://www.fossnet.de/treuchtlingen.php . Thomas 1 Be not ashamed of mistakes and thus make them crimes (Confucius, 551 BC - 479 BC).

If you mean the features below, these are so-called "dendritic" mineral formations. Link to comment Share on other sites More sharing options...
