Ammonite from Ukraine

Hi guys, i've receiced those ammonites from @Svetlana, they are sinemurian.

I tried.to figure out what species they are.

Note that the carena is well marked for all of them and they all show costulations.

 

For that first one i found nothing but Oxynoticeras or Asteroceras, i'm absolutely not satisfied about that.

For the second one i've found Echioceras rhodanicum

And for the  third one Orthechioceras maybe cf. viticola

Hello, Sophie.

Great job! I didn't think that these ammonites could really be identified.
Thank you!

For the first one, i found an article in research gâté : https://www.researchgate.net/topic/Fossils/publications?_tp=eyJjb250ZXh0Ijp7ImZpcnN0UGFnZSI6InB1YmxpY2F0aW9uIiwicGFnZSI6InB1YmxpY2F0aW9uIn19 by Bogdan A. Zaitsev about the Sinemurian-Pleinsbachian ammonites from the Bodrak River basin in Crimea and i found that the genus Tropidoceras is a better match.

The article speaks about Tropidoceras semilaevis and erythraeum.
