So, I was looking at some PAX screenshots of the phylogenetic tree area in the museum and I think there maybe space for a new fossil. First off, some of the silhouettes lead down to that species' extinct relative, like the elephant silhouette going to the mammoth and the cat silhouette going to (what is likely) the Smilodon/sabertooth cat in this photo.
In this photo, you can see the rhino silhouette go down to (again what is likely) the Megacerops, the deer silhouette leads to nothing, and the space where the player can stand also leads to a stand with nothing on it. I'm willing to bet the human space leads to where the Peking Man will sit, so that leaves the deer sihouette. Currently, we don't have any fossils that are related to deers in the game. Megaloceros/Irish elk fossil incoming, maybe?
