Some of you might remember me from this thread last year. My first question regarding this year is: "Where did you guys get all of your taxonomy information relating to all the different organisms?"
For my other event I've been using itis.gov, but I've found this ineffective for Fossils. What have you guys been using? Are there any "Holy grail" websites that you have been using to study and find invaluable pictures of specimens? Thank you all!!!
I haven't found a good all-inclusive website for Fossils; I just scan multiple sites until I decide on what's most likely going to be used.

For this question I shall quote myself in a past post. I hope this works for you!

Hi. I have a question:
What is the difference between Gryphaea and Exogyra in physical appearance. I saw the two fossils and could not tell them apart. I know that they live in different time periods, but when it comes to the event you have to identify fossils. I they show me a fossil of a coiled bivalve I can't tell if its Gryphaea or Exogyra.\
So anyone can give me a good description of the physical diffrence between Exogyra and Gryphaea? Thanks

This doesn't always work, but Exogyra has sort of a rough shell to me. Also I think they have slightly different sizes, although it's hard to tell size in pictures.

My partner said on one of the tests she was asked to identify the subphylum of something event though in the rules it said we only need to know kingdom, phylum, class, order, family, genus, and species. Should I include subphylums, superphylums, infrakingdoms etc. in my binder?

You probably should, since it only takes up a few lines in your binder and tests might ask for it even if it's against the rules; the binder is for the obscure stuff that you can't memorize. Also, subphylum vertebrata is on the list, as well as others similar, so it probably is allowed to be asked.
BTW, 'phylum' and 'genus' are pluralized 'phyla' and 'genera' (Latin spellings, don't question).

Any tips on differentiating Equus from Mesohippus based on the skull only? What about the teeth?

The eye socket for Equus is higher on the skull than Mesohippus's. Equus teeth are also very flat, versus Mesohippus, which are crowned.
