Major Reclassification of Dinosaurs Proposed

A team of researchers in Britain did a new analysis of hundreds of dinosaur skeletons and  have concluded that the current classification of dinosaurs into two major groups called the Saurischia (“lizard-hipped”) and Ornithischia (“bird-hipped”), first proposed in 1888, is not correct.  Read More →

Huge Skull from Alaska Supports Legends of Ancient Giant Polar Bear

An extremely large bear skull (dated to about 1,300 years ago) found in 2014 on a beach in Alaska could belong to a giant type of polar bear described in legends by Arctic people as distinct from and bigger than modern polar bears.

New Early Jurassic Marine Fossil Lagerstätte Found in Alberta

Paleontologists use the German term Lagerstätte [storage place] for fossil sites with exceptional preservation and abundant fossils. Such deposits are rare worldwide. Stonerose in Washington state is considered an example of a Lagerstätte for plant fossils.  Now a new Lagerstätte for marine animals (invertebrates and vertebrates) has been found at Ya Ha Tinda in Alberta, Canada, and dates from the same time period as similar marine fossil sites in Italy, Germany, and  Great Britain. The special preservation (including soft tissues) may be the result of low oxygen levels in the water at the time, preventing decay before the animals were buried in sediment.

New Fossil Crabs From British Columbia and Oregon

Homolid crabs (known as “porter crabs” or “carrier crabs” ) are long-legged, deep water crabs that get their common name from carrying sponges, corals, and even urchins on the back of their carapace using a special pair of legs, a behavior thought to be a defense or camouflage against predators.  Their fossils have been rare from the West Coast.  A new paper names describes  a new genus of homolid crab (Cretalamoha) from the Pender Formation on Vancouver Island in British Columbia and a new species (Paromola roseburgensis) from the early Eocene Roseburg Formation in Oregon.  Another fossil homolid crab named Homola vancouverensis was found in the Eocene Hoko River Formation of Washington State and described in 2001.

Evidence Claimed of Humans in Yukon in Canada as Early as 24,000 Years Ago

The DNA evidence from Kennewick Man and from other even more ancient human remains adds support to a theory that a genetically distinct human population developed in the Bering Strait region on an exposed land area called Beringia that connected Siberia and Alaska when sea levels where lower during the Ice Ages.

Kennewick Man Reburied by Local Northwest Tribes

On February 17, 2017, members of Northwest tribes came to the Burke Museum and took the remains of Kennewick Man, which had been stored at the museum since 1998. The next day (February 18), the tribal members reburied the “Ancient One,” as he was called, in a ceremony at an undisclosed spot on the Columbia Plateau.  This brings a formal end to a long legal and cultural dispute that brought scientists, the federal government, and tribal peoples into conflict over the 9,000-year-old human remains found along the Columbia River in 1996.
