Ask A Curator: Q&A With Paleobiologist Ken Angielczyk

Being a curator at a natural history museum can include many different areas of work, from doing research and studying collections, to field work and training future scientists. Dr. Ken Angielczyk, an associate curator and paleobiologist at The Field Museum, shares some of the unique aspects of his work. Ask @FieldMuseum all your natural history and science questions on Wednesday, September 14, for #AskACurator Day! What does being a curator mean to you?

How well do you know SUE?

The towering Tyrannosaurus rex that greets visitors at The Field Museum is hard to miss. But how well do you really know SUE? To celebrate SUE’s Unearth Day on August 12, the date she was discovered, we’re brushing up on some essential facts: Who is SUE? Even though we refer to SUE as a “she,” it is unknown whether this T. rex was female or male. We know that this carnivorous dinosaur lived about 67 million years ago and probably weighed nine tons during its life.

Extreme Animals Competition: Glyptodont v. Ironclad Beetle

In the Extreme Animals Competition, we’re looking at some of the fastest, fiercest, and strongest members of the animal kingdom. In the Armored Defenders category, the extinct glyptodont and the extant ironclad beetle are known for their built-in body armor. Glyptodont: Walking suit of armor Vital stats: 

Newly-discovered dinosaur had “T. rex arms” that evolved independently

Scientists still aren’t sure why T. rex had those absurdly small forelimbs, but apparently the look was all the rage in the Late Cretaceous. A newly-discovered dinosaur from Patagonia has similar short, two-fingered claws, even though it’s not closely related to the tyrannosaurs.

Four Fossil Sharks That Are Cooler Than Megalodon

Megalodon is the T. rex of the prehistoric shark world—it might have looked like a Great White, only way, way bigger, and it’s everybody’s favorite. It’s had its moment in the sun, even starring in a fake Shark Week documentary saying that it’d been found in modern waters (don’t worry—megalodon has been extinct for millions of years). But The Field Museum is home to some really bizarre sharks that lived millions of years before dinosaurs were even a twinkle in the universe’s eye.

A Breakup with Lasting Impact: Meteorites from a 470-Million-Year-Old Split

The residents of a Chicago suburb were jolted awake just before midnight on March 26, 2003—by meteorites falling through their roofs and windows. The Park Forest meteorite, named for the area at the center of the shower, fell in one of the most heavily populated areas to see meteorites in recent history.

Revisiting “Jurassic Park”: Could dinosaurs really be cloned?

“Where do you get 100-million-year-old dinosaur blood?” asks Dr. Ellie Sattler, a character in the original “Jurassic Park” movie. In the film, dinosaurs are cloned from DNA preserved in amber. More specifically, from dinosaur blood inside mosquitoes that are trapped in the amber. Spoiler alert: things get a little out of hand as the cloned dinos wreak havoc on Isla Nublar.

Mammals began their takeover long before the death of the dinosaurs

It’s a familiar story—the mighty dinosaurs dominated their prehistoric environment, while tiny mammals took a backseat, until the dinosaurs (besides birds) went extinct 66 million years ago, allowing mammals to shine. Just one problem—it’s not true. A new article in the Proceedings of the Royal Society B reports that mammals actually began their massive diversification ten to twenty million years before the extinction that ended the age of the dinosaurs.

Dueling sabers: What this marsupial has in common with a cat

Saber-toothed cats such as Smilodon are easy to recognize, thanks to their long, sharp canine teeth. But saber-toothed cats had an unexpected lookalike: something more closely related to a kangaroo than a cat. Thylacosmilus was a saber-toothed mammal most closely related to marsupials, living in South America between seven and three million years ago. The marsupial’s young would continue developing after birth, while the placental saber-toothed cat gave birth to developed offspring.
