Arthropleura could reach 2.7m and 50kg

Arthropleura could grow up to 2.7 meters long (think: as big as a car) and weighed around 50kg, making it even larger than ancient sea scorpions.
According to Neil Davies from Cambridge University, fossils like this are rare and usually incomplete; this one's probably just a shed skin.
While scientists haven't found its head yet, they think it may have fed on other invertebrates and small vertebrates such as amphibians; nuts and seeds were available in the leaf litter.
This discovery gives us a cool peek into an era when massive creepy-crawlies ruled the land.
