I have a level 314 spino, her name was Waterspout. She was very dark blue. She helped me collect bio toxin, and meat and hide from other creatures. One day I went out with Waterspout in the open ocean to collect some resources when my game crashed. I quickly logged back in and fortunately I was still alive, but I didn’t find Waterspout. I didn’t find her dead body or anything that makes me sure she died. I drowned after a while for running out of stamina. So I respawned at my base, grabbed my ichthyosaurs and searched for hours, but no clue. I didn’t get any death notification either. I hope I find her soon :(
