Well, not really, I just thought this was a pretty cool article. I love this kind of nature stuff
Experiments by a team of researchers in New York and New Jersey have generated evidence that questions the common belief that the pterygotid eurypterids (“sea scorpions”) were high-level predators in the Paleozoic oceans. This group, which ranged the seas from about 470 to 370 million years ago (long before the dinosaurs appeared), included the largest and, arguably, scariest-looking arthropods known to have evolved on planet Earth.
Reaching lengths of 2 ½ meters with a body supported by well-developed legs, and armed with a pair of forward-facing claws laden with sharp projecting spines, they seem like the Tyrannosaurus rex among the invertebrates.
Two and a half meters? Whoa! The article goes on to question whether they could really be high level predators, due to constrains in their ligature. If you find this as interesting as I do (and I do) read the whole thing. And think about them when you go on your winter vacation to some warm water island.
