A viral clip appears to show a group of tiny dinosaurs running across a beach but can you work out what's really going on?

After a few seconds the more boring reality becomes clear - they're actually mammals called coatis and the clip has been played backwards.

The original footage was recorded by Raphael Medeiros Braga in Brazil on April 24.

"That video was recorded at Itaguaré Beach,” said Medeiros Braga.

"When I looked at the small preview in my camera roll, it looks like there are so many dinosaurs, so I had the idea to reverse the video, and I posted it first on TikTok," he said.

"It explodes there, then I put it on Instagram and it explodes there too,” he added.

"Dinosaurs?" You must be shocked right now, or perhaps happy and excited.
Or you may begin to doubt the video and its authenticity, and your excitement may start to fade.
Maybe you want this clip to be accurate because you've been a huge dinosaur fan since you were a kid.
You could also believe that a new species, similar to baby dinosaurs, has been discovered.
Sorry for dumping all of your wonderful ideas and excitement.
These aren't dinosaurs or newly discovered species.
These are monkeys crossing water.
Yes, this is just an editing feature; the footage is in reverse motion.
