An Iguana, a Tortoise, an alien skull and child skeleton, mummified and fossilized alien animals, skulls, bones, dead rats, rodents and fish fossils. From the guy who first found the "Iguana on Mars" back in April 2013 - ArtAlienTV. Even this more recent remake pre dates UFO sightings Daily by over 2 months.
Many of these objects are probably just strange volcanic rocks that were solidified in an interesting shape when they landed in water but some of them have legs. The tortoise is quite clear as it is not too small or far away.
It is the size of a Galapagos tortoise from Earth and is walking away from the camera and looking back at it. The long neck is clearly above the ground as you can see from the shadow. It's shell and legs are also quite clearly defined.
There are two dead rats in this Mars video. There are probably more that are a bit too small like the one at 1.11 minutes - to the centre right above what looks like a snail about to feed on the rat corpse.
