ARK announced plans to add new features like creature breeding and baby dinosaurs. The update notes found here also mention a new dinosaur heading to the game, the Mosasaurus. 

The update notes go into detail regarding the use of breeding new dinosaurs:

Also from the update notes, the “Terror of the Deep” (the Mosasaurus) is coming to ARK. The Mosasaurus is described as being “is the largest creature that lives within the ARK’s vast ocean”. The notes go on to describe some interesting uses for the Mosasaurus, one of which is “to build mobile aquatic bases upon it’s back”. The new features will give players more ways to play and hopefully survive.
