Mantelliceras Posted October 6, 2017 Share Posted October 6, 2017 Hello everyone! I found many fossils in my last trip to a mountain in Valencia, Spain (as far as I know the strata in that mountain are Jurassic/Cretaceous) but I can't identify these 4 fossils displayed in the pictures below. I would appreciate any help, thanks!. Link to comment Share on other sites More sharing options...
jpc Posted October 6, 2017 Share Posted October 6, 2017 the top one looks like a Baculite, but I would have to see sutures on it to be sure. Link to comment Share on other sites More sharing options...
Fossildude19 Posted October 6, 2017 Share Posted October 6, 2017 Second item may be an imprint of a Pinna type clam shell.

NWGeoFan Posted October 6, 2017 Share Posted October 6, 2017 The top one could be a baculite, but it looks like a fossil I found on the Oregon Coast in the US that i got identified as a pelagornis humerus, if you could take pictures of the ends that would be great 1 "I am going to dig up dinosaurs whether they are liquid or solid" Link to comment Share on other sites More sharing options...

NWGeoFan Posted October 6, 2017 Share Posted October 6, 2017 Doesnt look much like a bone structure from the picture i would agree with baculite. Do you have a magnifying glass you could hold up to your camera to get some close up pictures? @Mantelliceras "I am going to dig up dinosaurs whether they are liquid or solid" Link to comment Share on other sites More sharing options...
Fossildude19 Posted October 6, 2017 Share Posted October 6, 2017 Doesn't look like bone to me...

Mantelliceras Posted October 6, 2017 Author Share Posted October 6, 2017 Yeah it doesnt look like bone to me either and if it's a baculites it's pretty worn out, cant really see shell, that's why I can't identify it well. I found another one near the first but smaller here are more pictures: Thanks for your help, appreciate it. Link to comment Share on other sites More sharing options...
Fossildude19 Posted October 6, 2017 Share Posted October 6, 2017 I'm thinking infilled burrow for the long one.

FossilDAWG Posted October 6, 2017 Share Posted October 6, 2017 The cross section of the long cylindrical specimen is surprisingly perfectly oval for a burrow. It could perhaps be a Baculites, with most of the specimen being living chamber which would account for the lack of obvious sutures. It may be of interest to see the narrower end in close-up to see if sutures are visible there. Of course this also all depends on the age of the rock. Does Jurassic/Cretaceous mean close to the Jurassic/Cretaceous boundary, or does it mean rocks of both Jurassic and Cretaceous age are present? Are Upper Cretaceous (say, Turonian-Mastrichtian) rocks present? Don 1 Link to comment Share on other sites More sharing options...
NWGeoFan Posted October 6, 2017 Share Posted October 6, 2017 You probably dont see any shell @Mantelliceras as it probably seperated from the structure when you removed it from the ground? This would leave the more solid filled center. "I am going to dig up dinosaurs whether they are liquid or solid" Link to comment Share on other sites More sharing options...

Are Upper Cretaceous (say, Turonian-Mastrichtian) rocks present? Don I'm afraid I cannot answer to your question accurately, being honest I dont think I know enough to determine wether the rocks are from jurassic period or cretaceous. It's a mining quarry at the mountain's slope and I can see different strata just by walking a few meters. There are jurassic and lower cretaceous for sure, but I cant be more accurate and in the worst scenary I even might be wrong. I took some pictures of the narrow end, also notice that It came out in many pieces that I had to glue together since the rock were very fragmented. 3 hours ago, NWGeoFan said: You probably dont see any shell @Mantelliceras as it probably seperated from the structure when you removed it from the ground? This would leave the more solid filled center. This is a picture of two fragments of the rocks where the pieces were attached. I cant see much left on them.

abyssunder Posted October 6, 2017 Share Posted October 6, 2017 I don't know if it helps, but a few years ago I've found in the Upper Cretaceous Gosau sediments of Romania some specimens similar to your long and flattened ones.

Ludwigia Posted October 7, 2017 Share Posted October 7, 2017 This is tough. I lean toward it being the steinkern of a baculite for 2 reasons. Firstly, the cross section shows an oval form which fits to the shape of Baculites and I've seen similar formations in the cretaceous of northern Germany which have been identified as such, and secondly, the structure looks too uniform to me to be the cast of a burrow. 2 Greetings from the Lake of Constance.

jpc Posted October 7, 2017 Share Posted October 7, 2017 I am all for baculite on this one. See Ludwigia's post just above, and in the touched up photo provided by FossilDude (Thanks, TYm) the bottom edge shows enough regularly spaced wavy edge for me to call it a bacuilite. Infilled shell,and very worn. I also see a Pen Shell (Pinna) in one of the other specimens. 2 Link to comment Share on other sites More sharing options...
