PMA Posted March 7, 2019 Share Posted March 7, 2019 This was also found near Herznach in Switzerland and according to my lexicon, it could be a Jurassic Holectypus, am I correct? Greetings! Quote Link to post Share on other sites
Tidgy's Dad Posted March 7, 2019 Share Posted March 7, 2019 It's a good fit, could be. But it's difficult, i'm trying to id a Jurassic echinoid at the moment myself, but mines a cidaroid, there are so many that look similar, and often the details of the lantern and so on are not preserved well enough to make ids very easy. 1 Quote Link to post Share on other sites
