Dinosaur Points (Also known as DP) are a form of currency received by converting Survival Points that you get by surviving and eating, drinking and etc. The more Dinosaur Points you have, the higher the conversion cost is. They are used to purchase more dinosaurs to play as such as the two most expensive dinosaurs of their respective categories, Amphicoelias, Gallimimus and Elasmosaurus. They do not have many uses other than unlocking new dinosaurs and simple bragging rights. It can take a few hours just to unlock enough Dinosaur Points for the Amphicoelias.
As of the time of writing, the person who has the most DP as of 2/14/2015 has a total of 29 DP.
