A Tyrannosaurus rex and a shark as neighbors? Yes, eons ago in South Dakota

Published

on

Scientists conducting a recent painstaking examination of the two tons of rock left over after the fossilized bones of the celebrated Tyrannosaurus rex named Sue were extricated in the 1990s came across a surprise: shark teeth.

The huge meat-eating dinosaur did not meet its demise in a shark attack in some sort of “Jaws” meets “Jurassic Park” monster mash. But, scientists said on Monday, when the 40-1/2-foot-long (12.3-meter) Sue died some 67 million years ago, the beast fell into a South Dakota river teeming with sharks – albeit small ones – thriving in the freshwater environment.

The skeleton of Sue, the largest, most complete and best-preserved T. rex ever unearthed, is displayed at the Field Museum in Chicago, which kept the leftover rock for years in underground storage. That rock has now yielded fossils from other creatures that were Sue’s neighbors including a shark species called Galagadon nordquistae.

Galagadon, related to a group called carpet sharks found in Indo-Pacific seas today, measured 1-2 feet (0.3-0.6 meters) long, with teeth the size of a sand grain, about four-hundredths of an inch (1 millimeter). Tyrannosaurus teeth were up to a foot long (30 centimeters).

If Galagadon ever interacted with Sue, it may have been when the thirsty dinosaur came to the river for a gulp of water.

“It would not surprise me at all if a T. rex individual scared a little Galagadon as it lowered its head to drink,” said North Carolina State University paleontologist Terry “Bucky” Gates, lead author of the research published in the Journal of Paleontology.

If Galagadon resembled its existing relatives, it was a blunt-faced bottom-dweller with barbels by its mouth like a catfish and camouflage patterning.

“The teeth have an unusual shape with three unequal points and a wide apron at the root. Some of the teeth bear an uncanny resemblance to the spaceship in the 1980s arcade game ‘Galaga,’ which inspired the genus name,” said co-author Pete Makovicky, a paleontologist and Field Museum dinosaur curator.

Scientists also are studying fossils of at least two other shark species from Sue’s river. Virtually all sharks live in the sea, though two freshwater species today reside permanently in rivers and lakes, and some other species venture into freshwater.

“I doubt Galagadon spent its whole life in freshwater habitats,” Makovicky said, suggesting its river may have been connected to an inland sea 100 miles (160 km) away that at the time split North America in half.

‘Go back to Harlem!’: Florida woman has n-word laced meltdown after bumping black woman’s shopping cart

On Saturday, the Atlanta Black Star reported an incident in Florida, in which a white woman screamed racial slurs at a black woman at a Publix supermarket in Miami after their shopping carts jostled each other.

After the woman allegedly banged into Nicki Johnson's cart, she refused to apologize, saying, "I didn't hit you with my cart, and f**k you,  you f**king n****r."

Johnson whipped out her cell phone camera, and began recording the incident, saying "You, why don't you call me a n****r again?"

"You thinking I'm sorry?" snapped the woman. "Let me tell you something, I don't have to call you anything. Get away from me, I will call security and there are surveillance videos. Get away from me!"

‘I’m a nurse, what are you?’: Tennessee lawmaker humiliates anti-choice activists in brutal public grilling

Published

on

Anti-choice activists in Tennessee were unprepared for the grilling they got from a Democratic Party lawmaker when making the case for a bill that would outlaw abortion before many women knew they were pregnant.

One of the speakers in favor of the fetal heartbeat bill was Baptist Pastor Randy Davis, who was questioned by state Sen. Katrina Robinson (D-Memphis).

"How many women executive pastors do you have in your convention?" Robinson asked Davis. "Or senior pastors."

"None," Davis replied.

"So is it the same ideology that restricts access to women being able to lead a congregation that leads you all to support women not being able to make a medical decision about their body?" Robinson asked.
