That page is one of the oldest parts of the website and I’m surprised it’s still linked to in the navigation actually. Its successor is the Observations search page, aka “Explore”, which is due for updating itself. If you click “Your Observations” in the main header, you can see, search, and filter a list of your observations, with darker icons:

They’re called “iconic taxa” - basically the main groups of organisms that most people think about when you start dividing up “life”.
