I dreamt up a hybrid dinosaur for the setting of Jurassic Park some time ago and just got around to creating them. Hybrids of the spitting dilophosaurus and the raptors. They have dextrous forelimbs and often hunt from treetops. They attempt to confuse or frighten predators and prey with the eye spots and mouthlike zigzag on their fanning frills. Smaller prey are eaten normally whereas large animals are killed and the abdomen has a mildly acidic venom spat inside and left to sit for hours. Not strong enough to dissolve all organs in serves rather as a tenderizer. After the internal organs are eaten the hollowed body is used as a shelter for eggs from the elements and creatures that would eat the eggs are warded of by the venom’s residual stench.
