Behold, one of Earth's earliest animals: Ok, so it's a flattened, circular blob with a mysterious question mark shape for a butt crack. A collaboration between US scientists and paleontologists ...
Blob is a very simple invertebrate, just like worms or jellyfish. Over 96% of all the animal species on Earth are invertebrate. They can be tiny like an insect or huge like the giant squid.
If we give Blob some legs and a head then he can start to move about. There are lots of vertebrates in the animal kingdom. Vertebrates are animals that have a backbone inside their body.
The animal had made a huge mess ... one veterinarian who did X-rays on the carcass compared it to a "brown blob" — but to territorial paleontologist Grant Zazula, it was definitely exciting.
