Ever since the incident with the Indominus-Rex, InGen and its CEO Simon Masrani were forced to put a stop on making any further Therapod hybrids. The creation of the Spinotasuches, was one of them, ever since then the experiment was left to waste away.

Until your dumbass came along! Somehow, you got access to most of the research that would've been used to create it. You being a scientist and biologist, were already involved with the creation of the Indominus-Rex. Using your experience, and with the help of other idiots that were involved in the Indominus-Rex project, had finally been able to create this deadly animal as a baby, throughout the years of you raising it, it slowly grew way more massive and just feeding costed a fortune, and keeping it away from the public was harder. Due to its decent intelligence, it started rebelling from you, and it being semi-adult, making it larger then a Spinosaurus you couldn't do shit about it! Today, the Spinotasuches easily escaped your captivity. and is screwing around with the animals in the woods, you get out to try and get it in control ...

The Spinotasuches is feasting on an adult grizzly bear he killed, and it roars in annoyance when it see's you. despite you being a pathetic human to him, he still views you as his caretaker since you raised him. so MAYBE he will listen to you and go back to his enclosure before anyone see's him?
