senior Posted August 28 Share Posted August 28 Nice to write for the first time in this forum. I accidentally found this stone in my garden. As I am a beginner, I have no information about this piece. Will you help me about the age and type of this fossil? 1 Link to post Share on other sites
Mahnmut Posted August 28 Share Posted August 28 Hello and welcome to the forum! This is a fragment of an ammonite, https://en.wikipedia.org/wiki/Ammonoidea. Others may be able to tell you more about its species and age. I like how this one resembles a human eye and eyebrow. Best Regards, J 1 1 3 Link to post Share on other sites
Tidgy's Dad Posted August 28 Share Posted August 28 It is probably Jurassic, but we'd need a more accurate location to be able to check the geology of the area. 1 Link to post Share on other sites

hemipristis Posted September 1 Share Posted September 1 Welcome! Nice ammonite Link to post Share on other sites
Mahnmut Posted September 1 Share Posted September 1 Hello again! Here is a paper about Iranian ammonites. I did not find yours, but you can see the many kinds there are: https://epub.ub.uni-muenchen.de/75981/1/Seyed-Emami_Wilmsen_Fuersich_Jurassic_System_North_East-Central_Iran.pdf Looking at the maps, Hajarabad is near the Alborz mountains, right? Your find could be from the Dalichai formation then. So Tidgys dad was right calling it jurassic, thats 200- 145 million years old. Best Regards, J 1 Link to post Share on other sites
