How to Name a Dinosaur (SciAm Guest Blog repost)

A year ago, I wrote a guest post for the Scientific American guest blog, called "How to Name a Dinosaur." Still kind of tickles me that I have my name associated with SciAm, even if it's such a minor way. So, here it is again.

You had no reason to expect a good weekend as you began a long-dreaded yard project. Come Monday morning’s office discussions of sporting events and parties, you would be nursing an aching back. But with a single strike of your shovel, your yard gave you a story to top any tale of drunken debauchery recounted over cubicle partitions: waiting less than 20 inches under the sod was a fossilized femur that hadn’t seen the sun in 120 million years.

Since plausibility has already been pretty well throttled, let’s say that in the kind of radically simplified form of paleontology children’s books employ, scientists from a local museum immediately recognize the bone as belonging to a dinosaur that is brand new to science. In a savvy move thought up by the museum’s public relations office, you will be given the honor of naming the beast. It’s a heavy burden, and you recognize quickly that it’s going to require careful deliberation. You don’t want your dinosaur to be laughed off of the paleontological stage, after all.

The name a dinosaur is given is subjected to the same scrutiny as the description of its skeletal remains. It’s a minefield, and there are many ways the unwary can go astray. A shaky grasp of latin might result in incorrect pluralization or an awkward suffix. Noble dedications to local culture and language can be misspelled. Worse yet, it might just sound silly. Avoid all of these, and your name still might be brushed off because you were too conservative.

As a first step, you might narrow down your choices depending on the kind of dinosaur you're naming. No matter what kind you've got on your hands, there is likely an informal signifier in the form of a suffix to its generic name. For an ostrich-mimic, you might choose -mimus. A herbivore with a beaked, horned, frilled skull receives a -ceratops. For a dromaeosaur, -raptor works nicely. To get across the tenacity of a predatory theropod, -venator sounds really cool. A relative of Baryonyx or Spinosaurus might pay tribute to the crocodiles its snout resembles with -suchus. Sauropods work well with -titan. To play it safe, choose the truly classic dinosaurian suffix, -saurus.

Generous fellow that I am, I’ll provide further guidance in the form of three broad categories which apply to most dinosaur names. Individual examples can bleed between them, of course. Since we’re about to turn the corner into 2011, I’ll also use the opportunity to employ some of my favorite dinosaur names of 2010 as examples. One note before I start: for brevity’s sake, I'm only giving advice for the generic half of the Linnaean binomial, in other words, the Tyrannosaurus but not the rex. You're on your own when deciding on a specific name. If you're stuck, name it for your mom, and you'll do alright.

Stick with Tradition

The 19th century scientists who founded the discipline of paleontology as we know it often stuck to simple anatomical descriptions of the fossilized creatures they examined. Gideon Mantell kept it basic with his Iguanodon, “iguana tooth.” Since he only had teeth to go on, we can’t fault him for lack of imagination. 1838’s Poekilopleuron simply means “varied ribs.” Joseph Leidy, the founder of American paleontology, chose Hadrosaurus as the name of the world’s first mountable dinosaur skeleton. It means “bulky lizard,” which is accurate, if not terribly evocative. 2010 saw the introduction of a few anatomically-named dinosaurs, such as the abelisaur Austrocheirus, the “southern claw.” Pneumatoraptor, from Hungary, was named for the tiny air pockets infusing its scapulocoracoid.

Considering the classical training of the early paleontologists, many of them had a firm grasp of mythology. Edward Drinker Cope’s Laelaps was named for a tenacious dog of Greek mythology - unfortunately, a mite had already been given the name, and it’s now the “tearing lizard,” Dryptosaurus. One of my favorite mythologically themed dinosaur names of recent years is the brachiosaur Abydosaurus, whose skull was found with four cervical vertebrae near the Green River at Dinosaur National Monument. Its name refers to the town of Abydos in ancient Egypt, where the god Osiris’ own head and neck were buried in the Nile. Instead of providing insight into the anatomy of the great beast it was given to, the name tells a story about its discovery millions of years after it walked.

A third subset of traditional names is to pay tribute to another researcher, fossil hunter, or someone else who was instrumental in the discovery of the dinosaur or the field in general. This is normally done in the specific name, but entire genera are occasionally dedicated to one person, as in the ornithischians Othnelia and Drinker, honoring the prolific rivals of the Bone Wars. Just this month, a North American troodontid named Geminiraptor saurezorum was announced, and both halves of the binomial are dedicated to a pair of scientist sisters named Suarez. If you’re familiar with matters astrological, you might correctly guess that they’re twins.

Go Native

If you want to be cutting edge, jump on to the growing trend of paying tribute to local places, culture, and history. It’s a heartening trend, as paleontologists often rely on locals for support of their work, and it counteracts the old stereotype of paleontologists ripping fossils from the ground for the enrichment of far-off institutions. And it engages cultures in ways that sticking stubbornly to Latin and Greek can’t. While the names of new dinosaurs coming out of China may confound the tongue of someone from Helsinki, Buenos Aires, or Des Moines, Chinese kids probably appreciate having dinosaurs of their own, such as Mei long, the “sleeping dragon.” On the other hand, local tributes can result in clunkers like this year’s dynamic duo Koreanosaurus or Koreaceratops, which recieved a fair amount of web snark.

This year has seen plenty of good newcomers in this category, though. A few of them paid tribute to the cultures who first inhabited the American West. Two of these derive from the Navajo language. Seitaad is named for a mythological beast that swallowed its prey in sand dunes, which also alludes to the manner of the small sauropodomorph's death. Bistahieversor’s name is derived from a Navajo description of local geography. The Zuni people have their own dinosaur as well, a duckbill named Jeyawati, which means “grinding tooth” in their language.

One of the most inspired members of this class of dinosaur names comes from Romania. When I first read about it, it sounded like some beast out of Tolkein’s Middle-Earth. But the island-dwelling theropod Balaur bondoc refers to actual mythology with a decidedly local flavor. It’s standard for descriptions of dinosaurs to include sections on the etymology of their names, but Balaur’s is exceptional, exploring the twisting roots of the word’s various meanings that approach the evolutionary tree of life for richness and complexity. Lead author Zoltan Csiki writes that Balaur’s name is “motivated both by the classical association between dinosaurs (especially theropods) and dragon-like creatures, as well as by the fact that balaur is a mythological creature with links to both reptiles (snakes) and birds (wings)...” Who knew that reading the description of a dinosaur could also be a lesson in Romanian mythology?

Make a Splash

It’s part of a paleontologist’s job to focus on the deep past, but some also think forward to the public impact of their discoveries. Lately, University of Chicago’s Paul Sereno has seemed especially focused on the public-relations side of paleontology; in 2009, he unveiled the controversial Raptorex, which might be mistaken for the name of a Pokemon character, as well as a slew of Mesozoic crocodilians with nicknames like BoarCroc, DogCroc, RatCroc, and the unfortunate PancakeCroc.

This year, even a mild-mannered iguanodont received an impactful name in Iguanacolossus. But 2010 will truly be remembered as the Year of Ceratopsians, and some of the catchiest new names come from the beak-and-horns set, including Medusaceratops, Kosmoceratops, and Mojoceratops.
One of my favorite dinosaur names of this year or any other is Diabloceratops, which describes the fierce twin horns protruding from the back of its frill and is just plain fun to say. If he was writing Jurassic Park today, I imagine that Michael Crichton would be strongly tempted to include a Diabloceratops paddock on the island.

A Final Word of Advice

Go bold. Shoot for a word that will make some emotional impact. A dinosaur’s name is often the first impression it will present to the public. Though the standard pantheon of the most popular dinosaurs - you know, the ones even my grandmother can name - has been in place for a century, it’s always susceptible to invasion by a charismatic newcomer, as was proven by Velociraptor’s leap into the public consciousness in the 1990’s. If a novelist, comic artist, or screenwriter latches onto the name of your dinosaur, it could very well be fast-tracked for celebrity.

Above all, remember that the name you choose for your backyard discovery will say as much about you as it does about the bones in the museum.

Diabloceratops eatoni, sitting pretty


Get a load of this great Diabloceratops by Andrey Atuchin, who goes by the handle Olorotitan at DeviantArt. Diabloceratops is another member of the ceratopsian class of 2010, a centrosaurine from late Cretaceous Utah. It's easy to be dazzled by Diablo's strange skull ornamentation, those two great barbs protruding from the back of its narrow frill. But its true importance lies in a more humble feature: two openings in the skull in front of the eye sockets called the antorbital fenestrae. These holes were lost in many subsequent ceratopsians; Scott Sampson has hypothesized that this may have been because greater skull strength was needed for possible wrestling matches between rival animals. Paleontologist Jim Kirkland's May 28 guest post at Archosaur Musings goes into great detail on this subject, discussing what the presence of that feature may mean in sorting out the ceratopsian family tree.

Big pat on the back to Atuchin for this beauty of a piece. I love the unconventional pose, the near-frontal view of the head, and the simplicity of the composition.

Ceratopsian Wrangling



Here's a roundup of links relating to some of the new ceratopsians we've been delighting in recently. Of course, many of the new taxa introduced in the last couple of weeks come from the long-awaited new book New Perspectives on Horned Dinosaurs: the Royal Tyrrell Museum Ceratopsian Symposium. The symposium was held in the autumn of 2007, and brought together a couple hundred experts in the field to share recent research.

Michael J. Ryan talks Medusaceratops lokii
The Vancouver Sun has an article about Medusaceratops featuring New Perspectives on Horned Dinosaurs lead editor, paleontologist Michael J. Ryan. Regarding the name he gave the new ceratopsian, he tells the paper, "One of the things I have a problem with as a paleontologist is how some of my colleagues come up with terribly unpronounceable names... I like to give my dinosaurs names that roll off the tongue and actually evoke an image." Hear, hear.

Jim Kirkland writes about Diabloceratops eatoni
In a guest post at Dave Hone's Archosaur Musings, paleontologist Jim Kirkland sums up what's cool about the new, also-wonderfully-named Diabloceratops. There are some fine photos of the skull, which is a thing of beauty.

Four foot horns from Mexico

Reconstruction by Lukas Panzarin

Coahuilaceratops magnacuerna is the new ceratopsian from Mexico, making news because of its enormous horns. I'd expect a story about it from Nat Geo soonish, as they partially funded the Utah Museum of Natural History dig.

Ojoceratops fowleri
The Bisti-De-Na-Zin Wilderness of New Mexico recently produced the tyrannosaur Bistahieversor, and now gives us Ojoceratops, a mid-size ceratopsian. Discovered by a team led by Robert M. Sullivan of State College of Pennsylvania, Ojoceratops gets its name from the Ojo Alamo Formation in which its bones were found. It's a controversial rock formation, as it is right at the boundary of the Cretaceous and the Paleocene, the first age of the post-dinosaur world. Paleontologist Jim Fassett has argued for years that dinosaurs may have survived a while after the Chicxulub impact based on fossils found in this layer. Sullivan has argued against this, so I doubt that any such assertions will be in the description. There's a great summary of the Ojo Alamo controversy at Laelaps; articles on Ojoceratops at the Santa Fe New Mexican and Pennlive.com.

These are the few that have received coverage; there are more that haven't had much written about them, including Rubeosaurus, Utahceratops*, and Tatankaceratops. I wrote a bit on Ajkaceratops and a bit more on Sinoceratops. A good place to keep up with recent discoveries, including plenty I haven't had the time to write about, is Dinosaur Central.

Finally, if you're a Facebooker, Ceratopsians have their own fan group, moderated by the Royal Tyrrell's Darren Tanke. More exciting than the Beyonce group, for sure.

*Kind reader 220mya has informed me that Utahceratops is not included in this title, and not yet described.

Hellraising Hornheads

You may have noticed a ridiculous number of news stories about ceratopsians - the beaked, frilled, frequently horn-sporting relatives of Triceratops - in the last week or so. Or maybe you don't have a Google Alert set up for "dinosaurs," in which case I should advise you to set one up ASAP. You'll be delighted by how much it raises your esteem with your peers.

Sober social advice aside, the hornheads have been popping up all over the place, due in part to the release of New Perspectives on Horned Dinosaurs from Indiana University Press. The book includes descriptions of a number of new species, including Diabloceratops eatoni, Medusaceratops lokii, and Coahuilaceratops magnacuerna. Coahuilaceratops is making waves for its enormous brow horns and for being Mexico's first ceratopsid, which is the largest, most lavishly ornamented group of horned dinosaurs.

Not to be outdone, China now has one of its own as well; it's named Sinoceratops zhuchengensis and is described in a new paper in the Chinese Science Bulletin. Both of these national firsts extend the group's known western North American range. Smaller, primitive ceratopsians like Psittacosaurus and Protoceratops are well-known from Asia, so the Sinoceratops discovery is especially significant. The authors of the study present their own revision of the ceratopsid family tree and state that the ceratopsians may have originally arisen in Asia, flourishing generations later in North America. The recently introduced Ajkaceratops - which was a member of the broader ceratopsian family - would seem to support this idea, as its ancestors were likely also of Asian descent.

If you want to impress people by picking a favorite dinosaur that's a little left-field, cool-looking and cool-sounding, you've got some solid options here. Personally, I'm going with Medusaceratops - check out the amazing Luis Rey reconstruction here.

Also cool is that the cover model for New Perspectives on Horned Dinosaurs is none other than LITC's patron dinosaur, Chasmosaurus. Cleveland Museum of Natural History paleontologist Michael Ryan, lead editor of the book, identifies the artist as the Royal Tyrell Museum's Donna Sloan.
