Introducing Washington's first dinosaur

Brace yourselves, dino-lovers: Burke Museum paleontologists have discovered the first dinosaur fossil ever found in Washington state!

The fossil is a partial left thigh bone of a theropod dinosaur, the group of two-legged, meat-eating dinosaurs that includes Velociraptor, Tyrannosaurus rex and modern birds. It was found along the shores of Sucia Island State Park in the San Juan Islands.

The fossil is approximately 80 million years old and is from the Late Cretaceous period. During that time, the rocks that today form Sucia Island were likely further south. How much further south is a topic of scientific debate, with locations ranging between present day Baja California, Mexico, and northern California. Earthquakes and other geologic forces that constantly reshape our planet moved the rocks north to their present-day location.

Burke Museum Curator of Vertebrate Paleontology Dr. Christian Sidor and University of Washington graduate student Brandon Peecook describe the find in the journal PLOS ONE.

As the Washington State Museum of Natural History and Culture, we're so excited to display Washington's first dinosaur fossil in our lobby and share the discovery with you!

Danny Shelton: Building cultural connections

University of Washington student and Husky football player Danny Shelton is a familiar face at the Burke Museum. As a student he completed several independent study courses at the Burke with Holly Barker, curator of Oceanic and Asian culture, building a stronger connection to his heritage in the process. During that time, Danny became an inspiration for his fellow classmates, encouraging them to utilize the Museum for their own cultural research and leading lessons about Polynesian culture for K-12 students at the Burke and beyond.

An article about Danny’s journey appeared in yesterday's Seattle Times. In the article, Holly said she's "proud of how [Danny] opened the museum's doors for many of his UW teammates, particularly the tight knit Polynesian players, to follow through on his work there." And she is proud. We all are!

As Danny prepares for the NFL draft tomorrow night in Chicago, we want to celebrate his time at the Burke and honor him for the work he’s done and the doors he’s helped open for so many others seeking connections to their cultural heritage.

The following is an excerpt from the introduction Holly gave Danny as the honored guest at our Curators Dinner this past Friday evening. 

We honor Danny for the many facets we have all come to know and love during his time at the Burke—attributes beyond his outstanding career as a Husky football player.

At the Burke, we honor...

Danny the Researcher, who initially came to the Burke with Hau'oli Kikaha and John Timu to explore the Polynesian objects in our collection, and to connect to and learn about their ancestry and traditions;

So this spider walks into a pine cone...

By Rod Crawford

On a sunny day in late May 2008, I went on a spider collecting field trip to Swauk Prairie outside of Cle Elum, Washington, with Laurel Ramseyer, a friend and field volunteer. The weather forecast called for "breezy." We'd have called it downright windy!

It was difficult to collect spiders with the wind blowing away anything loose and exposed. I did manage to sift nine spider species from hawthorn leaf litter, but only swept six species from the rippling sea of grass. Laurel had similar troubles.

Then Laurel saw a spider run into a large fallen pine cone (probably to get out of the wind), so she picked up the pine cone and started to whack it inside her net in an attempt to collect the spider. It worked! We were in a Ponderosa pine woodland with a lot of pine cones so she continued whacking more cones and eventually added three good species to that site's spider list.

This small beginning led to a major obsession for Laurel and she began using this method at other sites. To date she has whacked nearly 7,000 pine cones inside a heavy-duty net held against her leg, looking for the pine cone spider fauna that she, in a sense, discovered. Laurel (with a little help from me) collected 1,060 spiders from 4,600 eastern Washington pine cones between 2008 and 2013. I identified the spiders and added them to the Burke's collection.

As it turns out, no spider species were previously recorded as collected from pine cones. Discovering a new spider species is relatively common, but discovering a whole new spider habitat—that's really something!

Some spiders evidently live in pine cones long-term, while others just use them to molt, lay eggs and rest when not out hunting. Or they wander in at random like that first one Laurel saw back at Swauk Prairie.

The spider we most commonly found in Washington pine cones was Euryopis formosa, a beautiful creature with a dark heart shape inside a bright silver patch on the abdomen. Sampling pine cones more than quadrupled the number of E. formosa specimens in the Burke spider collection—it was found at 47% of sampling sites!

This was the first study to describe the spider fauna of fallen pine cones and now there are 89 species recorded in our published paper, including two species never found in Washington state before.

Spiders are everywhere—even in pine cones!

Studying hybrid lizard species through DNA

by Jared Grummer 

I often wonder what non-scientists think of my research: why would people care about lizards that most will never see? When I say I study hybrids, do they think I mean hybrid cars? Hybridization, or interbreeding between distinct species, of lizards in Argentina is a very foreign idea for most, in more ways than one.

Origin of the Seahawks logo: The story unfolds

It’s been one year since we first explored the connection between a Native mask from the Pacific Northwest and the original Seattle Seahawks logo. What a year it has been! Now, as the Seahawks prepare to "re-Pete" their visit to the Super Bowl, here’s what we’ve learned so far about the mask that inspired the logo.

A collection of Washington state symbols, natural history style

On Nov. 11, 2014, Washington state turns 125. In the spirit of celebrating, we highlighted 12 objects in the Burke collections that are quintessentially Washington—at least according to the Revised Code of Washington (RCW), a compilation of all laws enacted by the state's Legislature.

Washington has 22 official state symbols to date under the RCW, and 12 of them can be found at the Burke Museum—the Washington state museum of natural history and culture since 1899. We care for these objects, and millions more, as a record of nature and culture to help us to understand how the choices we make today will affect the future.

Here are the 12 Washington state symbols in the Burke collections:

State Tree: Western Hemlock

The western hemlock (Tsuga heterophylla) is found in Washington's temperate rain forests. This evergreen conifer can grow up to heights of 230 feet, with the longest living specimen being more than 1,200 years old; it became the State Tree in 1947. Fun fact: new-growth needles can be steeped to make vitamin-rich tea. Date collected: May 6, 1967.

Digging for fossils in the Petrified Forest

By Tom Kaye

The sky was crystal clear as my wife Carol and I geared up for our first day “on expedition” at Petrified Forest National Park in northern Arizona. This trip was particularly exciting for us because Petrified Forest had recently acquired a huge new tract of land and we, along with several colleagues from the Burke Museum, were the first team going in to look for fossils!

Specifically, we were looking for fossils of huge predators from 210 million years ago during the Triassic Period. We knew that most of the fossils we found would belong to extinct groups known as aetosaurs and phytosaurs. The former sported armor plates and foot-long spikes to ward off attacks. The latter were the Triassic equivalent of crocodiles: aquatic predators that you didn’t want to mess with.

Hunting for fossils isn’t as glamorous as it’s cracked up to be. It was never less than 100 degrees on the desert floor thanks to the sun’s reflection. We wore SPF 50 sunblock made for children so it didn’t sting when the sweat runs in your eyes. We were almost never in sight of anyone else. And the best fossils are ALWAYS the farthest from the truck.

So, I hope you enjoy the pictures and know that you’re getting the best parts of the trip right here!
