First time I saw them at first I thought they were big compys. I didn't notice their glowing eyes because of the fireflies. These things can jump. One knocked me out when it launched onto my raft. Forget fighting these unless you're out of reach.
Me and my Carnotaurus went out on an adventure together for the first time and around 4 troodons and a raptor attacked us. He couldn’t attack them because because his turn radius is bad, so I jumped off to try and save him from dying. After I respawned I went back with my pteranodon to try and get my stuff back but before I could escape my carnotaurus and my pteranodon died (a dilophosaur snuck up on my pteranodon while I was trying to save my carno) which left me stranded to die again. I will never go back there again. 1 up=1 prayer for Carnold and Petrie
