They're not hybrids
They're not hybrids they're not hybrids they're not hybrids. I'm pretty sure that this island was Ingen's first ever project at creating dinosaurs. They couldn't even fathom the possibility of an Indominus Rex, as it appears that these dinos were conceived before any of the ones we see in JP. This island is in the Carribean, far far away from where we know Nublar and Sorna are, so after these failed experiments, they abandoned ship and moved to a new island to start afresh with their findings from this one. The Scorpios Rex was the first attempted hybrid. The new mutant we saw was not supposed to look like this, but they were doing something that no one had ever done before. It's probably their first ever attempt at a carnivore, and then they eventually developed the process before leaving this island for Sites A and B. They had their failures here (the weird monster thing, the double headed raptor, and more we will see) and then left them to die as they left. Ingen probably couldn't even sequence the ability to make all the dinos female, hence the eggs that are present here. I know that this isn't what some of you wanted, but these are NOT HYBRIDS.
