But seriously, how quickly could a giant sauropod dinosaur react to an attack on a body part 150 feet from its brain? The excellent blog SV-POW! has the answer:

… sauropods really did have individual sensory nerve cells that ran from their extremities (tip of tail, soles of feet)–and from the rest of their skin–to their brainstems. In the longest sauropods, these cells were probably something like 150 feet long, and may have been the longest cells in the history of life. We haven’t found any fossils of these nerves and almost certainly never will, but we can be sure that sauropods had them because all vertebrates do, from hagfish on up. That’s just how we’re built. So how long does it take to send a nerve impulse 150 feet? The fastest nerve conduction velocities are in the neighborhood of 120 meters per second, so a signal from the very tip of the tail in a 150-foot sauropod would take about half a second to reach the brain…[continue reading]

One of 2 completed pieces for a Human Genetics and Development assignment Graphite, each around 7”, some more imagined than others (don’t count ribs too carefully ;) ). I’d like to print around 11x14” cephalothoracopagus, craniopagus, parapagus
