guess the dinosaur

As you know, I have been writing a series of stories caled Jurassic World raptor evolution story, and when I submitted my last story I announced I was making a new series of stories, called Jurassic World dawn of chaos. The new series of stories is set when the D. Rex breaks out. I am giving people the chance to put an idea of theirs into my story. All you have to do, is tell me what dinosaur I am describing and post a picture of it, if you guess right, I will put your suggestion in my first story. Please don't make a innapropriate suggestion, and don't kill someone off. The dinosaur is a relative of coelophysis, and it is from the triassic period. It has a quality that it shares with dilophosaurus (dilophosaurus is a coelphysid). Good luck.
