Okay so my thought goes as following: Some birds are known for having a feeling of rythm and can be seen swinging along with music. Birds are somewhat related to dinosaurs. So if you could travel to the past with some nice music, there is a non 0 chance that you could dance with some dinosaurs (before being eaten).
Oh my gosh, brb gonna invent time travel to teach a T-Rex the phrase “Poly wants a cracker” or die trying.
Pretty sure you’d die REALLY quickly.
