You are a scientist that was in on a experiment to make time traveling possible, you were in the lab working on the type of fuel you need to time travel, that fuel is called L.B., Liquid Blue. You went to lunch to have your food until with the other scientists when the Leader scientist said on the speaker...

Leader Scientist: "Scientists 126-245, come to the lab immediately, the project is 97% complete."

You went to the lab and saw all of the other scientists preparing for the big moment, when the portal will open. You grabbed some L.B. and poured it into the portal and in steady beeps, 98%, 99% and 100%. The blue portal opened, a bright blue light coming out of it, meanwhile a kid got loose in the building and went into the lab and accidentally pushed you in... you got time jumped 210 million years from the present day into the ocean and the portal closed, you went to the surface but noticed a Helicorprion (a massive shark with a swirl tooth). The shark noticed you and started swimming towards you, until a massive creature rammed it's gills, killing it, it was a Shatasaurus (massive fish like creature with long nose), it had a scar over its eye, and was very big. It was about to attack you when you made a hand gesture meaning "I'm not bad". The shatasaurus seemed to be timid and it looked like it trusted you now, it shook its head, gesturing you to follow it. What do you do? Follow, or swim away?
