New Members GEORGE-GR-68 Posted February 3, 2021 New Members Share Posted February 3, 2021 Hi forum ! Many thanks for accepting me and very glad to join Please help ID this fish. I have no any knowledge in fossils weight of rock 1795 gr. Length of rock 330 mm, width 109 mm, height 33mm, length of fish 287 mm ( without the possible horn with horn approx. 295 mm ) , height 82 mm. Please notice in the photo of the rock that I have poured water on it, the fish seems to have some kind of a horn in front of its head. Possible Creataceous period ? Origin: My father in merchant navy had bought it in Brazil Thanks for any answers Link to comment Share on other sites More sharing options...

Those are actually gill bones at the back of the head. The head is not visible. 1 Link to comment Share on other sites More sharing options...
Top Trilo Posted February 3, 2021 Share Posted February 3, 2021 Can't help with species but you gave great information which will make an identification much easier for those who know their fish, and welcome from Colorado USA “If fossils are not "boggling" your mind then you are simply not doing it right” -Ken (digit) "No fossil is garbage, it´s just not completely preserved” -Franz (FranzBernhard) "With hammer in hand, the open horizon of time, and dear friends by my side, what can we not accomplish together?" -Kane (Kane) "We are in a way conquering time, reuniting members of a long lost family" -Quincy (Opabinia Blues) "I loved reading the trip reports, I loved the sharing, I loved the educational aspect, I loved the humor.

Rockwood Posted February 3, 2021 Share Posted February 3, 2021 Just noticed that it is pictured belly (ventral) side up. Hope I don't come across as being too rude. Just the facts as I see it. 1 Link to comment Share on other sites More sharing options...
New Members GEORGE-GR-68 Posted February 3, 2021 Author New Members Share Posted February 3, 2021 hi, thank you for all the comments. Yes excellent remark, stupid me ! Yes since it's a fossil and the characteristics are not very clearly evident , it did never cross my mind, that I had it upside down and what seemed to be a horn, looks actually a half head. I downsized images, rotated and I repost. Can the new pictures assist to ID this ? Link to comment Share on other sites More sharing options...
Rockwood Posted February 3, 2021 Share Posted February 3, 2021 Time is what is needed now I think. More knowledgeable folks will probably weigh in soon. Link to comment Share on other sites More sharing options...
Fossildude19 Posted February 3, 2021 Share Posted February 3, 2021 Welcome to the Forum. This looks like a Tharrhias araripis. Brightened and contrasted: Some professional preparation may be able to expose more of the skull. 3 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

New Members GEORGE-GR-68 Posted February 3, 2021 Author New Members Share Posted February 3, 2021 many thanks, based on some photos I jest checked on the web for this Tharrhias araripis. , there are many similarities so it has been a great help !

Does it look as if the head might be rotated to expose more the ventral surface than is apparent ? The twist being somewhat obscured by the sectioning of the fish by the split. These fish are typically found by splitting concretions. Link to comment Share on other sites More sharing options...
Fossildude19 Posted February 3, 2021 Share Posted February 3, 2021 Not sure. But the outlined areas appear (from the picture, at least) to be covering the bulk of the skull, if it is still there.

Fossildude19 Posted February 4, 2021 Share Posted February 4, 2021 It is possible there is still more under there.

Rockwood Posted February 4, 2021 Share Posted February 4, 2021 I think it could probably could also be that the concretion just wasn't quite big enough to include the whole fish. Isn't there like a window/envelope of opportunity for preservation created by the formation of the concretion soon after burial ? Link to comment Share on other sites More sharing options...

There could have been predation or disarticulation due to decomposition. Fish heads and bellies are pretty commonly found "blown up or apart" from gasses produced during decomposition, prior to fossilization. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."
