Best way as a beginner or higher up player to survive these guys is to tame a sinamocrops (using chitin), Sina’s sit on ur shoulder and screech at anything small, including troodons, seagulls, dilos, and more. I think Sinas are only on lost island, but they are definitely worth it!
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
