What happened to Dilophosaurus?

Maybe Dilophosaurus died out, It had competition too.

I have been doing some researching, the dilophosaurus primarily ate fish, aquatic invertebrates, carrion, and small vertebrates.

Also I have been reading the dilophosaurus form (the crests) was present in many early jurassic theropods, I wonder if the dilophosaurus went extinct through evolving into more advanced theropods.

Yeah, I can see both happening. As for compeition, I think the odds were low since the Early Jurassic ecology was just recovering from the End Triassic extinction
