According to Qpaniic and a dozen more Reddit users. The Season 5 theme could be hinted as early as now at the start of Season 4.
With Dinosaur footprints located around the island, a Dinosaur logo at the end of battle pass season 3 and skins such as Rex and Tricera Ops. They might now be that far from the truth.
What do you think? Season 5 is the Dinosaur Age?
