RJB Posted May 18, 2020 Share Posted May 18, 2020 This concretion was actually from a fossil trip last year. Its two ammonites in one rock but the bigger ammo has half of its beak right in front of the appature. Amazing. These are known as Rhaeboceras halli and are from the Bearpaw Shales of eastern Montana. He brought it over to my garage and wants me to 'clean' it up.

FossilNerd Posted May 18, 2020 Share Posted May 18, 2020 Awesome Ron! Looks like you may have raised yourself a decent fossil hunter!

Fossildude19 Posted May 19, 2020 Share Posted May 19, 2020 Hey Ron, Is it a beak, or is it an Aptychus ? Either way, it's a cool find. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

RuMert Posted May 19, 2020 Share Posted May 19, 2020 RJB obviously refers to the aptychus seen on the right, which is part of the lower half of the ammonite jaw apparatus akin to the coleoid beaks. Why not indeed? My sites & reports Link to comment Share on other sites More sharing options...

Ash Posted May 19, 2020 Share Posted May 19, 2020 If it is a beak then it’s massive for the size of the animals. Cephalopods tends to have tiny beaks for the body size.

Ludwigia Posted May 19, 2020 Share Posted May 19, 2020 I beg to differ. If that's an Aptychus, and it appears to be one even though the photo's a bit blurry, then it would have no problem fitting into the mouth aperture. Nautilae have beaks. The function of Aptychae has been undergoing debate for years. 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

I was basing my answer of squid so probably not a good idea. 1 "Faith is to believe what you do not see; the reward of this faith is to see what you believe" - Saint Augustine"Those who can not see past their own nose deserve our pity more than anything else."

caterpillar Posted May 20, 2020 Share Posted May 20, 2020 If it is an aptycus, it does not correspond to the size of the aperture of the ammonite http://www.paleotheque.fr Link to comment Share on other sites More sharing options...
