The shapes of fossilized teeth from 65.9 million-year-old, squirrel-like creatures suggest that the branch of the tree of life that gave rise to us humans and other primates flowered while dinosaurs still walked the earth. That’s the claim coming from a team of 10 researchers across the U.S., including biologists at Seattle’s Burke Museum and the University of Washington.
In a study published by Royal Society Open Science, the team lays out evidence that an ancient group of primates known as plesiadapiforms must have emerged before the mass-extinction event that killed off the dinosaurs. (Technically, modern-day birds are considered the descendants of dinosaurs, but that’s another story.)
The evidence comes from an analysis of tooth fossils that were unearthed in the Hell Creek area of northeastern Montana.
Washington Gov. Jay Inslee and other dignitaries got a helping hand from a troop of third-graders today when they cut a hand-woven cedar ribbon to mark this weekend’s opening of a spacious new home for the Burke Museum of Natural History and Culture.
The students from University Temple Children’s School, just across the street from the museum site on a corner of the University of Washington’s Seattle campus, represented the next generation at the ribbon-cutting ceremony — just as they did at the New Burke’s groundbreaking ceremony three years ago.
“One, two, three,” Inslee counted, and then he cut the ribbon with a giant scissors that was also held by UW President Ana Marie Cauce. The kids snipped their classroom scissors at the same time.
Museumgoers will be able to nosh on frybread tacos at the Off the Rez Cafe. They can feast their eyes on totem poles and other artifacts from Northwest tribes. And they’ll have the chance to reacquaint themselves with their favorite items from the old Burke Museum building, which has now been replaced by a parking lot.
Stein, whose new office isn’t far from the T. rex, doesn’t miss the old place at all.
“The old building was very difficult to live in. It was the lack of air conditioning and the lack of humidity control. The facility was falling apart. The restrooms were inadequate,” she recalled.
“Inviting the public into a place that was shabby was disheartening,” she said.
In contrast, Stein is excited about the opening of the New Burke, which was built right next to the old museum site, on the western edge of the University of Washington’s campus.
“I just can’t wait for the visitors to come,” Stein said.
Tyrannosaurus rex may have reigned as “king of the tyrant lizards” 65 million years ago, but 185 million years before that, a reptile about the size of an iguana was the king of Antarctica.
At least that’s the message contained in the name of a fossil that’s described in a newly published research paper — and is now part of the permanent collection at Seattle’s Burke Museum of Natural History and Culture.
In the mastodon’s case, we’re talking about a creature that lived 10,000 years ago. But when it comes to the New Burke, we’re talking about a modernistic, airy museum that’s 66 percent larger than the Old Burke next door.
The exterior construction part of the $99 million project is essentially complete, and the next phase — creating the exhibits and workspaces, and transferring an estimated 16 million objects from the Old Burke to the New Burke — will begin within just a few weeks.
To mark the transition (and kick off a fundraising campaign), the Burke’s staff gave journalists as well as museum members and donors a first look at the new building, plus a behind-the-scenes look at the collections in the 56-year-old building that currently serves as the museum’s home.
The only Tyrannosaurus rex skull to go on public display in Washington state is getting its unveiling at Seattle’s Burke Museum of Natural History and Culture – and the best part is that you can watch as more and more of the skull is revealed.
“You can see those teeth coming out,” University of Washington biologist Greg Wilson, the museum’s curator of vertebrate paleontology, told GeekWire today at the big reveal. “And those teeth are gorgeous.”
As he spoke, a team of paleontologists and trained volunteers worked methodically in a glassed-in room, chipping at and brushing away the rock and sand that surrounded the fossil skull.
Seattle’s Burke Museum took delivery of what’s recognized as one of the finest Tyrannosaur rex skulls in the world today, but there are still more bones out in Montana to add to the treasure.
“We’ll go back again,” Greg Wilson, a University of Washington biologist who led the excavation team at Montana’s Hell Creek Formation, told GeekWire at the arrival ceremony. “There’s more in the hill.”
It’ll take more than a year to do the preparatory work on the skull and more than 50 other T. rex bone specimens that have been recovered over the past couple of months, including vertebrae, ribs, hips and lower jaw bones.
The haul so far appears to account for about 20 percent of the complete skeleton. That puts the Burke Museum’s set of fossils among the world’s top 25 T. rex finds, Wilson said. He told reporters that the museum’s T. rex skull will be the only one to go on public display in Washington state.
Paleontologists from Seattle’s Burke Museum of Natural History and Culture have discovered the fossil remains of a Tyrannosaurus rex, including a 4-foot-long skull, and they’re bringing the goods home with them.
The plaster-encased dinosaur skull, which weighs 2,500 pounds, will be unloaded from a flatbed truck at the museum on Aug. 18.
The Burke Museum says the research team excavated the reasonably complete skull, as well as pieces of the T. rex’s lower jawbone, vertebrae, ribs and teeth, during this year’s field season at the Hell Creek Formation in northern Montana.
