Arthropods trump dinosaurs, again!

By laelaps on February 27, 2008.

ResearchBlogging.orgBy now most of you are probably familiar that this blog takes its name from a tyrannosauroid dinosaur originally named Laelaps by E.D. Cope but changed to Dryptosaurus by O.C. Marsh when it was discovered that the name Laelaps was preoccupied by a kind of mite. According to a taxonomic note in the latest issue of the Journal of Paleontology, a similar change-up is now in order, this time involving the ceratopsian dinosaurs Diceratops (Lull, 1905) and Microceratops (Bohlin, 1953). As it turns out, both Diceratops and Microceratops were originally applied to insects in the order hymenoptera (wasps, bees, ants, etc.), Diceratops in 1868 and Microceratops in 1952 (making it a very close shave between the dinosaur and the arthopod).

A further wasp in the paleontological ointment is that (as far as I am aware) we're still waiting for a good description of Diceratops and for more material as the existence of this genus is somewhat controversial; some think it should be folded into Triceratops but others consider it to be a valid genus. For now, though, using Diceratops for the dinosaur is right out, and in order to help preserve the feel of the name (and reduce confusion) Octavio Mateus has proposed Diceratus as a replacement. Likewise, Microceratus is proposed as a replacement for Microceratops, although the validity of this genus, too, has been called into question. Oh. what a tangled web we weave...

[Update: ReBecca also covered this change at her blog.]

Bully for Brontosaurus
Much is being made of Brontosaurus. Brontosaurus is a genus name for a large dinosaur, known to watchers of “Land Before Time” as “Long-Necks.” That generic name dates to the 19th century, but in the early 20th century it was eliminated as a proper Linnaean term and replaced with Apatosaurus. This…

A close-up of the Triceratops mount on display at the AMNH. Ornithischian dinosaurs don't often get much attention, perhaps because some groups (i.e. hadrosaurs) are often viewed as the "cows" of the Mesozoic, having almost the exact same body plan only differing in head ornamentation. Members…

Aw geez, not again! Those durned pesky bugs should all have some sort of prefix to avoid confusion, like '[Bugus]insignificatus pointlessi'. That'd get dem bugs of our lawn!

Exactly, John. ;) All those entomologists are just hoggin' all the good names.

Then again, I do like the -ceratus suffix; makes the name sound a bit more impressive than the standard -ceratops.
