    I honestly wouldn’t have a clue as to the identity of this specimen. My knowledge is limited to the areas I collect.

    Certainly for many of us trying to keep up with the most current taxonomy is a challenge. Even amongst the professionals they are only as good as their own specialty. What I try and tell other collectors is that they shouldn’t get too hung up on having every order, class or family figured out. In fact just getting a fossil identified to genus…[Read more]

    • Very good rules to live by! My specialty is in blastozoan echinoderms and I’ve been venturing into Cenozoic mollusk taxonomy and it gives me such a headache!

    Well now that is all confusing. I just revised it to match the Echinoid Directory (Smith & Kroh, 2011) which has always been my go to for fossil echinoids. And I should have checked that against what the “MyFossil auto-fill” inserted. I’m going to compare the three: iDigBio, PaleoBioDB and the Ech Directory…

    • I’ve struggled a lot with taxonomy recently (mostly of mollusks) and have been checking all the databases I can. I think the Echinoid Directory likely has the most updated classification as it was generated by the experts working on echinoid taxonomy & evolution.

    • Hi, @erich-rose – I always like to see echinoderms entered into the database! The PBDB suggests Euechinoidea as the order (which is different from iDigBio). Is echinoid ordinal taxonomy undergoing (or requiring) some work?

    Hey Jen,

    That is called the apical cap. In many regular echinoids it includes the periproct (=anus) as well as the genital pores. In many regular echinoids the apical plates get scattered after death and we just see a large opening. But some types feature an apical system that takes the form of a cap-like assembly of plates. The “Salenias” are…[Read more]

    • That is so fascinating! Thank you for taking the time to explain that to me and I look forward to checking out more of your collection!

      Jen
