Newly Discovered Dinosaur Named After Monster From 'Ghostbusters'

The last time a newly discovered species of club-tailed dinosaur wandered the Earth was 75 million years ago. But when researchers at Canada’s Royal Ontario Museum saw the fossil, their minds went to 1980s science fiction. As the Los Angeles Times reports, Zuul crurivastator is named after the ferocious demigod from Ghostbusters (1984).

Z. crurivastator shares a few characteristics with the movie villain, as the researchers lay out in their new study published in the journal Royal Society Open Science. It has four legs, a snub nose, and horns that flare from its crown and face. The second half of its name means "destroyer of shins," a nod to the bony weapon it carried on the end of its tail. Z. crurivastator has this characteristic in common with the rest of the Ankylosaurus genus.

Unlike Zuul, this dinosaur didn’t hang out inside refrigerators and on top of skyscrapers. The 5500-pound herbivore spent its days grazing the landscape and clubbing predators in what is today the badlands of northern Montana. A fossil-hunting company came across its remains while excavating another dinosaur in 2014. After hitting its tail with a bulldozer, they dug further and discovered an intact skull. The specimen is the most complete North American Ankylosaurus fossil on record.

After the bones were turned over to the Royal Ontario Museum, scientists made another exciting discovery: Portions of the soft tissue had been preserved for millions of years, possibly due to the sediment that surrounded it. Paleontologists plan to test the scales and sheath around its spiky armor for molecular traces of keratin. The analysis could lead to revelations about the color and makeup of dinosaur skin.

Prehistoric Ticks Once Drank Dinosaur Blood, Fossil Evidence Shows

Ticks plagued the dinosaurs, too, as evidenced by a 99-million-year old parasite preserved inside a hunk of ancient amber. Entomologists who examined the Cretaceous period fossil noticed that the tiny arachnid was latched to a dinosaur feather—the first evidence that the bloodsuckers dined on dinos, according to The New York Times. These findings were recently published in the journal Nature Communications.

Ticks are one of the most common blood-feeding parasites. But experts didn’t know what they ate in prehistoric times, as parasites and their hosts are rarely found together in the fossil record. Scientists assumed they chowed down on early amphibians, reptiles, and mammals, according to NPR. They didn’t have hard evidence until study co-author David Grimaldi, an entomologist at the American Museum of History, and his colleagues spotted the tick while perusing a private collection of Myanmar amber.

The tick is a nymph, meaning it was in the second stage of its short three-stage life cycle when it died. The dinosaur it fed on was a “nanoraptor,” or a tiny dino that was roughly the size of a hummingbird, Grimaldi told The Times. These creatures lived in tree nests, and sometimes met a sticky end after tumbling from their perches into hunks of gooey resin. But just because the nanoraptor lived in a nest didn’t mean it was a bird: Molecular dating pinpointed the specimen as being at least 25 million years older than modern-day avians.

In addition to ticks, dinosaurs likely also had to deal with another nest pest: skin beetles. Grimaldi’s team located several additional preserved ticks, and two were covered in the insect’s fine hairs. Skin beetles—which are still around today—are scavengers that live in aerial bird homes and consume molted feathers.

“These findings shed light on early tick evolution and ecology, and provide insights into the parasitic relationship between ticks and ancient relatives of birds, which persists today for modern birds,” researchers concluded in a news release.

Extinct Penguin Species Was the Size of an Adult Human

A penguin that waddled across the ice 60 million years ago would have dwarfed the king and emperor penguins of today, according to the Associated Press. As indicated by fossils recently uncovered in New Zealand, the extinct species measured 5 feet 10 inches while swimming, surpassing the height of an average adult man.

The discovery, which the authors say is the most complete skeleton of a penguin this size to date, is laid out in a study recently published in Nature Communications. When standing on land, the penguin would have measured 5 feet 3 inches, still a foot taller than today’s largest penguins at their maximum height. Researchers estimated its weight to have been about 223 pounds.

Kumimanu biceae, a name that comes from Maori words for “monster" and "bird” and the name of one researcher's mother, last walked the Earth between 56 million and 60 million years ago. That puts it among the earliest ancient penguins, which began appearing shortly after large aquatic reptiles—along with the dinosaurs—went extinct, leaving room for flightless carnivorous birds to enter the sea.

The prehistoric penguin was a giant, even compared to other penguin species of the age, but it may not have been the biggest penguin to ever live. A few years ago, paleontologists discovered 40-million-year-old fossils they claimed belonged to a penguin that was 6 feet 5 inches long from beak to tail. But that estimate was based on just a couple bones, so its actual size may have varied.
