How do you get more miracilous fossil rocks?

Put on one of the color masks and go where you know there aren't many/any vivosaurs of that color. For example, the red mask and Icegrip plateau, or the yellow mask and hot springs heights. This way, you only dig up jewels dark and wondrous or miraculous rocks. Many of the dark fossils you dig up will be dropping fossils. A secondary goal of this plan is to get lots of dropping fossils. What! Am I crazy? No, I'm not , but the guy in the Hare Club on Cranial Isle sure is! When you play the Waste Not, Want Not side mission (see the info guy at any shop for details), he'll give you a miraculous rock for each 20 dropping fossils you give him. Since you get the @&$@& things whether you want them or not, this is a great way to put them to use. I think I have 27 or 28 of the superevolvers so far and most of my gold fossils came from John Guano at the Hare Club. Hope this helped. Good luck.

Go to treasure lake with pink mask from dp then dig up dark fossils most have dropping fossil why the heck do you want those well john guano in hare club next to guild in cranial once you give him 20 or something he gives you mirqculous every time keep doing this and you will get jewel rocks

Those are some other good ways but another way is to get two masks red & green make sure you have a fully upgraded sonar and all the cases then when you put one of the mask [example] green mask go to MT KRAKANAK and find the yellow dote [by the three brothers] and it should be a dark fossil, miracules,wondorus HOPE IT HELPS
