Dinosaurs of the Year: 2014 Edition

Updated on February 5, 2018

During the first week of September, a 65-ton dinosaur from Argentina made the headlines and homepages of many American news sources. For laymen, this may have been a welcome distraction from ISIS, Ukraine, and other bad news at home and abroad. For dinosaur devotees and experts, this and a few other new genera described this year have the potential to alter and broaden our perspective of these animals as a whole.

Like a similar article I wrote at the end of last year, this list doesn't discuss every dinosaur discovery since January. Instead, it spotlights the most substantial, mold-breaking genera named and presented to the public in 2014, after years of rigorous excavation, preparation, and examination by their discoverers.


Anzu (North and South Dakota, 68-65.5 million BCE)

Since the 1920s, most oviraptorosaurs have been found in Chinese or Mongolian deposits. Paleontologists have also identified North American species of these strange, beaked theropods, though usually from fragmentary fossils. Between 1998 and 2013, however, fossil hunters collected four separate specimens of a new genus from the Hell Creek Formation. Like other Hell Creek dinosaurs (such as T. rex and Triceratops), Anzu was one of the largest, last, and most completely-known of its kind.

Though colorfully called "the Chicken from Hell" by various news sources, Anzu actually takes its name from a bird-like being from ancient Mesopotamian mythology. In life, adults would have stood well over six feet tall and weighed about a quarter of ton--much bigger than most oviraptorosaurs and second only to its Mongolian relative Gigantoraptor. Its dramatic head crest, stunted tail, larger hands, and broader feet also separated Anzu from most of its Asian kin. This latter feature may have helped the animal negotiate the coastlines and wetlands it inhabited, in contrast to the smaller feet of Mongolian desert-dwellers like Citipati.

Dreadnoughtus (Argentina, c. 75 million BCE)

Dreadnoughtus may not be the largest known dinosaur. Among the candidates for this title, however, it is easily the most complete.

Between 2005 and 2009, paleontologists led by Kenneth Lacovara excavated two separate specimens of this titanosaur in the Patagonian province of Santa Cruz. These excavations yielded nearly half of the total skeleton, including most of the limbs, rib cage, and tail. Lacovara's team even found a Dreadnoughtus tooth and part of the muzzle--an amazing discovery in itself, since most sauropods are found without a trace of their comparatively tiny, fragile skulls. Dreadnoughtus' remains may prove crucial in helping paleontologists better understand titanosaurs as a whole. Though known from every continent but Antarctica, their fossils are generally much cruder, making the task of determining their core characteristics and evolutionary relationships a huge challenge.

Estimated to have reached about 85 feet long and 65 tons, Dreadnoughtus takes its name from the dreadnoughts--giant warships deployed during World War I. Beyond alluding to its size, Lacovara gave this herbivore the name for another reason: The term "dreadnought" literally means "fears nothing", and like modern African elephants and rhinos, he believes that adult Dreadnoughtus would have been extremely powerful, dangerous beasts with little to fear from the local large predators.

NOTE: Dreadnoughtus is not to be confused with another newly-discovered Argentine titanosaur covered by news sources this year. This still-unnamed dinosaur was found in Chubut (the province just north of Santa Cruz), lived roughly 20 million years earlier, and seems to have been even bigger.

Kulindadromeus (Russia, c. 169-144 million BCE)

For the past twenty years, paleontologists have unearthed and unveiled a multitude of feathered dinosaur fossils. Most of these finds concern advanced theropods, blurring the line between these hollow-boned, bipedal dinosaurs and birds (or, if you prefer, non-avian and avian theropods). Feathers or feather-like structures, however, are also known in a few ornithischians, a separate order of dinosaurs that includes the stegosaurs, hadrosaurs, and ceratopsians. Until now, the only confirmed examples were the ceratopsian Psittacosaurus and the heterodontosaur Tianyulong, both of which had tails lined with long, quill-like structures.

Kulindadromeus ("runner from the Kulinda fossil site") lacked the specialized beak, armor, or horns that characterize many ornithischians. But fossils of this diminutive Jurassic herbivore do preserve traces of filaments as well as scales. These filaments include not only lone fibers, but multiple structures branching from single stems, emulating the display and flight feathers of advanced theropods and modern birds. Since Kulindadromeus sits near the trunk of the ornithischian family tree, conceivably every member of this diverse group could have had ersatz or genuine feathers. Since feathers are so well-represented among theropods, these structures may even have been common to dinosaurs as a whole.

Qianzhousaurus (China, c. 70-65.5 million BCE)

Since 2009, paleontologists have described at least one new tyrannosaur genus each year. This year, they unveiled two: Nanuqsaurus ("polar bear lizard") from Alaska and Qianzhousaurus ("lizard from Qianzhou") from Jiangxi. Both grew to be around twenty feet long and lived about 70 million years ago. Yet while Nanuqsaurus' skull seems to have conformed to the thick-toothed, deep-skulled profile of T. rex and its close relatives, Qianzhousaurus had thinner, more numerous teeth and a set of longer (and probably weaker) jaws that earned it the nickname "Pinocchio Rex". This dinosaur also had a more pronounced set of horn-like structures lining its snout than other late tyrannosaurs.

The description of this strange predator supports the idea that smaller, slender-snouted tyrannosaurs coexisted with bigger, deeper-jawed genera at the end of the Cretaceous. Along with Alioramus--a Mongolian contemporary that also had beaky jaws and prominent horns--Qianzhousaurus may have hunted oviraptorosaurs and small ceratopsians. This strategy would have prevented it from directly competing with the much larger and more robust Tarbosaurus, just as modern cheetahs avoid confrontations with lions. It also may have spared these predators injuries from more dangerous dinosaurs like titanosaurs.
