                                      Big clawed fossil had spider like brain
Wow can you believe that Scientists have discovered the best preserved nervous system in an ancient fossil. Scientists say the fossil dates back 520 million years ago and the clawed fossil shows clear evidence of the brain and nerve cords running through the creatures trunk. Nerves in this fossil seems to be similar between major groups of animals. Now lets learn some more things about the fossil. Can you believe all thanks to this fossil we can finally confirm that the ancestor of spiders and scorpions are related to each other. 


You are probably wondering where scientists found this fossil.Well this fossil was found in South China.But the most amazing part is that this fossil is a part of Alalcomenaeus a group which has segmented bodies and a dozen pairs of appendages which allow these creatures to swim and crawl.OK the last thing I have to tell you about this fossil is that that these creatures are from a extinct group of marine arthropods that are know as megacheirans in "Greek for large claws". Well guys what do you think about this story? Well to me I thought this was a pretty interesting story because now we can finally confirm that the ancestor of spiders and scorpions are finally related. Sorry guys I have to leave so bye.
