I had a lvl 32 spino and my other two lvl 28 spinos they frikin killed everything in the water next to my base, they killed megalodon, megapirhnas, and killed some fish, and they killed a frikin alpha mosa, NO JOKE!
I was once taking a stroll with my baby ROXY (a trike) down the memorable south zone 3 in the island. We watched as dusk came upon us, but then... I notice a floating rock moving towards us, to late to realize it's a spinos back. I ran as fast as my small legs could, but roxy was too fat. I had to leave her behind. It reminded me of those videos of Nile Crocs catching prey. Don't mess with no Spinos.
