Well, that depends on how one defines language.

No, it doesn't.

Pangaea or Pangea ( /pænˈdʒiːə/[1]) was a supercontinent that existed during the late Paleozoic and early Mesozoic eras.[2][3] It assembled from earlier continental units approximately 335 million years ago, and it began to break apart about 175 million years ago.[4] In contrast to the present Earth and its distribution of continental mass, Pangaea was centred on the Equator and surrounded by the superocean Panthalassa. Pangaea is the most recent supercontinent to have existed and the first to be reconstructed by geologists.

I know when Pangea assembled and when it fragmented.   The question is what level of communication sophistication are animals of that era capable of, and at what level of sophistication would we call the communication language.

Maybe dinosaur language?

Well, 3 things.  

1.   Many dinosaurs have anatomical features interpreted to support specialized vocalization. 

2.   One branch of dinosaurs is directly ancestral to birds, and likely possessed brains organized similarly to birds.

3.   Of all animals ever studied, babbler birds come closest to having a human like auditory language.  Closer than possessed by any extent primate.   https://www.sciencedaily.com/releases/20...152230.htm


This doesn’t prove any dinosaurs had language precursors.    But if you were to ask me whether it is plausible that babbler like capability for language precursors may have existed in bird lineage all the way back to non-avian dinosaurs,  I would say nothing rules it out.
