I doubt we need many more of the other types of fossils, but there could be so much more done with the large sized fossils. I am currently building a science center in the game, and I was gonna put a T-Rex fossil in there because it reminded me of the St. Louis Science Center I went to as a child which had giant an Animatronic T-Rex and Triceratops. Triceratops is iconic and I definitely feel that having a large Triceratops fossil would make the game much more enjoyable. You wouldn't want too many more large fossils, because it'd become very difficult to find all of their pieces. However, if you added, say, a Triceratops and 2 more cool looking alien type fossils, I'm sure everyone would enjoy it and it'd definitely make me feel nostalgic with my science center memories. Thanks!
