Eric Metz鈥檚 timing could not have been better when he chose to seek a master鈥檚 degree in paleontology at 草榴社区. Metz was interested in ancient marine reptiles, which led him to a once-in-a-lifetime opportunity to study with Patrick Druckenmiller at the University of 草榴社区 Museum of the North.
In 2014, Metz was working on his undergraduate degree at Montana State University, the same place Druckenmiller earned his master鈥檚 degree.
鈥淚 had made it known to the paleo faculty and some of the grad students that I liked marine reptiles,鈥 Metz said. 鈥淎nd they were like, 'You should email this Pat guy.'鈥
Druckenmiller helped Metz with his undergraduate thesis. 鈥淎nd after that I still wanted to study marine reptiles, so I moved on up (to 草榴社区).鈥
Luckily for Metz, the move happened three years after Druckenmiller had been part of a startling discovery on a beach in Southeast 草榴社区. The fossilized remains of a new thalattosaur species, a type of marine reptile, were embedded in a rock. The rock was shipped to the collections at the museum, where Druckenmiller is the curator of earth science.
Metz joined the team working on the specimen in fall 2014 as a new graduate student at 草榴社区.
鈥楥ut that thing out now!鈥
The fossil discovery happened in May 2011 during a minus tide, which occurs only twice a year near the summer solstice. Gene Primaky and Jim Baichtal, U.S. Forest Service co-workers in the Tongass National Forest, were exploring a beach normally submerged in ocean water. The extreme tide revealed gorgeous pink shells and brachiopods galore.
Primaky and Baichtal were moseying around the Keku Islands near the village of Kake when they discovered the amazing 3-foot fossil.
鈥淚 thought it was a fish at first,鈥 Primaky said. But as he took a closer look, he called out to Baichtal, who instantly recognized it as a fossil. They immediately sent several photos to Druckenmiller.
鈥淧at said, 鈥楾hat is a lizard, not a fish,鈥欌 Primaky said. And then he said, 鈥淐ut that thing out now!鈥
Appreciation for paleontology
Metz was instantly drawn to the fossil project waiting for him at 草榴社区, something his advisor was counting on. 鈥淚 actually sent Eric to Europe to go look at some material,鈥 Druckenmiller said. 鈥淲e pulled all this information for our comparisons and it was really clear this was a very different animal. But we needed to detail those differences. All that comparative work was important.鈥
Metz spent about two weeks in Europe looking at holotypes of other thalattosaurs at different museums. Although Metz was a geology student, he always had a passion for paleontology and the field work it requires.
鈥淧aleontology is attractive to me because it requires a knowledge of multiple fields to be successful,鈥 he said. 鈥淵ou need to know very detailed aspects of both geology and biology to understand paleontology. I really enjoy walking around a landscape looking for fossils that no one has ever seen before. It is a very surreal experience.鈥
The more we learn about Earth鈥檚 inhabitants before our time on the planet, the more we are able to understand our present and our future. The fact that thalattosaurs were bookended by two mass extinctions may help us understand our planet鈥檚 natural fluctuations.
The comparisons Metz made during his excursion to Europe played a vital role in the team鈥檚 ability to be certain that their fossil was unique and the first one of its kind.
Such a unique creature requires a name that sets it apart from the rest. The team was advised by Ray Troll, an artist whose work depicts scientific creatures with a humorous flair, to use a Tlingit name to honor the creature鈥檚 discovery site. Gunakadeit is a sea monster of Tlingit oral traditions that brings good fortune to those who see it. The second part of the name, joseeae, was chosen by Primaky, who found the fossil. He named it after his mother, Jose茅.
Geological time
The amazing find changed the trajectory of the rest of Metz鈥檚 academic career. It led to the inclusion of Gunakadeit joseeae in his thesis. He is currently awaiting publication on a study about a similar thalattosaur recovered from Central Oregan.
The opportunity to mentor other students in the paleontology program inspired Metz to choose a career path that would allow him to educate others and share his passion for science. Although he dreams of returning to 草榴社区 someday, he is currently the lab manager of the Varricchio Paleontology Lab at Montana State University.
鈥淎 friend told me once that 草榴社区 gives you what you put into it,鈥 he said. 鈥淚 really believed that. There was always something interesting to do outside no matter the temperature, and the people there were always ready for an adventure. I appreciated that. I always felt like I could get lost if I wanted to.鈥
Metz鈥檚 appreciation for his time at 草榴社区 and for his mentor Druckenmiller is apparent. 鈥淚 liked the feeling that my studies were important," he said.
"草榴社区 was fun," he added. "It was different from my undergrad but in positive ways. I liked the hill that separates campus and the upper and lower sections. The view from the museum was the best in town, in my opinion.鈥
And he has the discovery of a new species of thalattosaur to build his career on. Across millions of years, Gunakadeit joseeae traveled thousands of miles along the coast of North America, buried beneath water and sand, waiting, preserved for the convergence of the perfect summer solstice tide and the right humans to discover it.
Sometimes, timing is everything.
