Creeping-death Giant-feet, 3-5 feet long Megapede dereponecis was the largest centipede to lived. Too heavy to haul itself very high into the trees, it hunted among the roots for small prey, including dinosaur chicks, which it quickly immobilized with its fierce and fast-acting venom. Mother M. dereponecis nested in rotten logs, chewing channels into the pulpy wood, where they laid eggs. They were particularly territorial during this time, attacking any intruders that threatened their delevoping offspring.
