For want of a prong, the genus was lost.

Thanks to the Hairy Museum of Natural History for the great plug. Having a wander through the site (it's about dinosaur fossils,after all) I stumbled across the story of how a fossil Seismosaurus was discovered, excavated, wrongly interpreted and reconstructed with an estimated length of 170 feet - 52 metres! Then some rethinking and vertebral shuffling shrank the creature to a feeble 110 feet. Then the experts had another look at some distinguishing features, moved a misplaced bone prong and with that, this particular Seismosaurus lost its unique (and very cool) and was relabelled as a large species of Diplodocus.

I'm not saying what follows because they've mentioned us. It's a great story, which illustrates how scientific method works and (more importantly) is written in a way which anyone would understand and find engaging. A model of what good science writing for the rest of us should be.

Donate, or the palaeo puns get worse.
