When Tamed they are like the iguanodons big brother which u can use 2 legs (slower but stronger) or 4 legs (Faster but weaker) and oh boi this guy is good in the swamps since titanoboas,barys,sarcos and kapro something will not agro to you if are only riding the spino and one more thing,this bad boy can get a lot of prime meat all you need to do is go to the swamp find a paracetheium or a lot of titanoboas and just go to 2 legs mode and kill all of them to get frickin 100 in 32 mins in my experience and basically it has a buff where if it's in a body of water (rain doesn't work)it's gets super strong that's why they bad boi can supply u some prime meat but it is bad on land (not on shores)
