I have my house near the red obelisk on the island. I was installing the floor for my second floor. I was returning home trying to tame a tapejara. I brought home a diplodocus egg. I stored it with my Iguanodon. The diplodocus followed me all the way home. My Carnotaurus, Camilla, was on the second floor with no walls. This diplodocus knocked Camilla off of my house and off the cliff. Thankfully she landed in the water. I killed the diplodocus to prevent further damage. After plunging into the water, I spent about 20 minutes getting Camilla back to my house.
