I knew this was coming. There was an interesting taxonomic consolidation recently: Torosaurus is accused of being simply an older Triceratops, so those two taxa are being lumped into one, Triceratops. Jack Horner is suggesting that Nanotyrannus was simply a juvenile T. rex. These kinds of adjustments of the taxonomy happen all the time, both as more data becomes available, and as lumpers make more noise than splitters (a process that can be reversed, of course). It is not a big deal.
Except to creationists, who are overjoyed that combining two species into one means that “the Ark cargo was even lighter than previously thought”. There’s also some crowing about those arrogant scientists being wrong wrong wrongity-wrong wrong ding-dong! Gloating over an occasional error would be much more impressive if they also ever acknowledged the many times scientists have been right, and the creationists wrong.
Like this time: a little taxonomical shuffling does not salvage the story of God and the big boat. Triceratops/Torosaurus are still 70 million years old, and the fact that dinosaurs underwent morphological changes as they matured deep in the Cretaceous does not suddenly make the idea that they were living in the Middle East 6000 years ago and taking a year long cruise any more plausible.
Maybe they’re just hoping that if the paleontologists keep consolidating taxa they’ll eventually get to the point where all the dinosaurs are lumped into one species called Behemoth. That’s not going to happen either.
