The dinosaur is more than 128 feet from nose to tail -- “with a head the size of a horse... hip muscles as big as a car... [and its length] longer than three school buses.”

The findings can help fill gaps in the tardigrades' evolutionary history, as they have managed to survive every mass extinction event.

“This behavior that we are seeing is coming thousands of years before [the] domestication of the chicken... [of] a huge, ornery, flightless bird that can eviscerate you.”

The microsaur's fossil, named after a mythical creature, will contribute to theories about origin of life on Earth, experts say.

Scientists found osteosarcoma — one of the most common types of bone cancer in humans — in the fossilized shin of a 76-million-year old horned dinosaur.

Scientists believe that fossil footprints made more than a 100 million years ago belong to crocodile-like animals that "ran like ostriches."
