Have paleontologists found any cephalopod fossils comparable in size to a giant squid?
How about giant spiders and/or scorpions? Also, millipedes and centipedes?
I do remember a giant dragonfly with a thirty-inch wingspread (from my childhood readings, not personal experience!). Have they found any bigger flying insects than that one?
The eurypterids were large relatives of scorpions that could get up to two metres long. Nothing impressive, but I thought I’d throw it out there.
Not impressive! A six foot long giant prehistoric scorpian with sharp pointy claws. The predator extrodanaire of the Iapetus ocean? Picture What would impress you?
The largest ammonite I could find is about 6.5 feet in diameter. That is coiled up - if you got 'em out of the shell you’d need a whole lot of batter and a lot of oil. They look like a Nautilus but don’t be fooled internally they are very different. They are also extinct. I can’t imagine things getting bigger then that - as far as invertebrates are concerned that made it to fossilization.
How about this? I remember it from another thread on this board but I can’t seem to find it now.
