Let’s just say that the dino that I’d bring back, time machine permitting, would be the biggest vegetarian that ever existed. It would be downright irresponsible to bring back a meat-eater. Haven’t we seen enough excitable movies on the theme of what can go wrong? The last genetic recreation humanity needs is one that would like to eat us.
If reptilian brains had advanced as fast as homo sapiens maybe the world would be dramatically different. Still, they had several hundred million years, and they wasted the lot. Thus, there’s not much to fear when faced with a large slow-moving vegetarian.
As the planet warms, so there will be more habitable regions where big plodding 40-ton dinos can do some good. A spectacle for sure. And a way to reshape landscapes. Driving evolution in the wilderness.
Here’s a crazy thought. The permafrost in Siberia is melting. Carbon is being released into the atmosphere. That’s not good. Let loose a lot of ultra-heavy dinos across such a wilderness. Feeding on the forests. Fertilising the forests. Equally compressing and churning up the soil. That might keep some of the carbon locked up.
Lusotitan monsters[1] wouldn’t threaten humanity. They might be an asset as well as being fascinating. Large herbivores exist today. We might value them more in the sight of a large dino lumbering across the terrain.
