The one on the right is complete and was found by Lesley Elliott. ©Drawing by Zack Pullen. This month instead of featuring one single fossil, I am featuring a whole bunch of them. Just like I was Time’s Man of the Year in 1966, along with countless others, this month’s fossils share the spotlight with each other. This past summer we started working on the eastern edge of Como Bluff again. The Tate Geological Museum had collected there decades ago, and it was about time we started up again. One of the sites we worked the most this summer was a site called “Claw.” This is a microsite ... an accumulation of mostly small bones of all sorts of animals from the Jurassic period. The vertebra above, found by Dwaine Wagoner, is one of the few large bones we found at this site. It is possibly from an Allosaurus. The top end got crushed before it was fossilized. To your right is a photo of the site with a small flock of volunteers working the productive layer, which is about 8 to 10 inches thick and runs horizontally for a fair ways. We spent quite a few days there on several trips with our field dig folks and our volunteers. Turtle pieces are by far the most common fossils here, and crocodile teeth come in a close second, but there is a great variety of bones to be found. Steve Pfaff spent a month or so cleaning the fossils we Below on the left is a well-preserved vertebra found by Melissa Connely. We have no idea what this one is from. On the right are four Allosaur teeth found by Steve Pfaff, Dwaine Wagoner, me, and Jane Berry.

Happy New Year – changes at the Tate – moving and remodeling Our neighbors in the building, the University of Wyoming/Casper College Center faculty, will be moving to new offices elsewhere on campus over the holiday break. This will free up three offices and two classrooms for use by the Casper College Geology Department and the Tate Geological Museum. We are planning on a little remodeling to provide a break room that is not in the prep lab and an alternative meeting room. We will also create space for exhibit design and development, a museum classroom, another geology classroom, and private offices for some of our staff. This will allow us a little extra space in the museum itself, which will be quickly absorbed by the gift shop. Tater Travels (Also known as J.P.’s travels – the rest of us are staying home) J.P. Cavigelli will be traveling to Fairbanks, Alaska at the end of January to do prep work on the Triassic marine reptile that was found in southeast Alaska, and is being studied by Pat Druckenmiller from the University of Alaska, Fairbanks. During the week of February 17, he will be traveling to Gainesville, Fla. for the North American Paleontological Conference where he will give a presentation regarding the museum’s use of volunteers to assist in excavating both Dee the mammoth, and Lee the T. rex. History of Paleontology – travel to Europe Imagine earning one to four credits by traveling to Europe. Visit famous museums, in London, Paris, Frankfurt, Tate Museum Geological Times by Deanna Schaff and numerous smaller local museums along the way. The participants will get a chance to do some fossil collecting as well. This trip will last for two weeks leaving Denver on May 17 and returning May 30, 2014. If you are interested in further information please contact one of the instructors J.P. Cavigelli or Melissa Connely at jpcavigelli@caspercollege. edu (307-268-3008) or mconnely@ caspercollege.edu (307-268-2017). Museum Lecture Series The Tate Geological Museum staff is planning another lecture series for the spring semester. The topic we have chosen is “Evolution and Extinction.” The talks will be held at 7 p.m. on Mondays, Feb. 10, Mar. 17, Apr.14 and May 12 (alternate date). We will be posting information about the individual topics and speaker information on our website and Facebook as planning is solidified. Big Brothers/Big Sisters Event Russell Hawley, education specalist, and Dominique Maestes, gift shop manager, spent some quality time at the Winter Wonderland sponsored by Big Brothers/Big Sisters on December 7. They report that there was a tremendous turnout in spite of the cold weather. The Casper College museums sponsored a table and Russell made origami dinosaurs for the kids and the Tate provided a dig box for their enjoyment. Both Russell and Dominique commented on the enthusiasm exhibited by everyone involved. Dates set for summer pay-to-dig adventures: Two pay-to-dig trips are being planned for summer 2014. The first to Como Bluff will be June 16 through 20. On September 15 through 19 a second group will visit the Lusk area to continue work on Merle, the hadrosaur. This lucky group will also have an opportunity to come early to attend the Denver Rock and Mineral Show the weekend of September 13 and stay an extra day and attend our biennial fundraiser on September 20. Judith Johnston received Werner Wildlife Museum Volunteer of the Year. A retired geologist who also loves birds was selected as the Werner Wildlife Museum Volunteer of the Year for 2013. Judith Johnston was presented the plaque at the open house held at the Werner on November 15, 2013. Judith started volunteering at the museum in January 2012 and has spent many days learning how to inspect, clean, and write condition reports for the Werner bird collection. In addition, she helped clean and catalog the Utzinger big horn sheep collection. Tater Talks to continue The museum staff selected dates for future Tater Talks for our volunteers. The dates are January 23, February 13, March 20, April 17, and May 15. If you are a Tate volunteer and have a question you’d like addressed or a topic of interest, please let J.P. know. Pizza will be provided on these evening talks, which begin at 6 p.m. The initial meeting on January 23 will include a planning session for the spring semester. Deanna Schaff and Judith Johnston 4 Holiday Open House – by Deanna Schaff About 450 people enjoyed the Holiday Open House and we were very pleased by the turnout. Excitement was in the air as children had their faces painted, hunted for shark teeth, made gifts for their parents and grandparents, threw balls through the holes in the cast of a T. rex skull, and made dinosaur Christmas ornaments. Many people took advantage of the photo-op with Santasaurus, took time to look at museum exhibits, ask questions, and go on special tours of the prep lab and Lee Rex Barn. None of this would have been possible without the help of numerous volunteers. Don Stagg was on hand to greet everyone at the front door and Dwaine Wagoner documented the fun on his camera. Santasaurus was played by Kristin Taylor and Con Trumbull answered questions and told stories about the museum exhibits. Steve Pfaff took groups on tours of the prep lab while our work study student, Steve Bennett (Fluffy), guided people through their tour of the Lee Rex Barn. The kids kept four face painters, Maryann Budenske, Melissa Stahley-Cummings, Lexi Brooks, and Sara Carr very busy. Lynne Swank was on hand to make sure everything ran smoothly in Room 121 as kids waited to have their faces painted, colored, and searched for shark teeth. The T. rex toss was managed by Lexie Finkle and Jeremiah Taylor. Becky Rothenberg helped Linsey Grant with our parent gift corner, and Nancy Doelger wrapped presents. I want to give many thanks to all of our volunteers. Many thanks also go to my hard working museum staff for helping me plan this event. They amaze me with their creative ideas and willingness to put forth that extra effort to turn the museum into a winter wonderland. Last, but not least, thanks to Kent Sundell for furnishing our 16’ to 18’ live Christmas tree. The smell of a fresh tree always pervades the lobby and compleats the holiday spirit. “Essence of Rex” by Chris Navarro Santasaurous (Kristin Taylor) with Tate volunteer Dwaine Wagoner.

Tate Museum Geological Times 5 Werner Wildlife Museum Art Show Results from the open house Werner Wildlife Museum One hundred fourteen people arrived at the Werner Wildlife Museum on Nov 15, 2013 to view the “NATURE” art show and enjoy our open house. Art created by Casper College students, faculty, and staff is still on display among the museum exhibits. The art will be kept in the Werner Wildlife Museum until Wednesday, March 19 so if you haven’t seen it yet, make sure you stop by. Tate Museum Geological Times 6 Exhibits Update: By Patti Wood Finkle, Exhibit Specialist ©Drawing by Zak Pullen. I am happy to announce that we have finished the Taxidermy Shop Exhibit at the Werner Wildlife Museum! Visitors now have a chance to step into a “real” taxidermy shop and find out what’s inside. Hopefully, the exhibit will answer any basic questions that our visitors have about taxidermy. It definitely answers one of the most often asked questions, “What’s inside the animals?” The exhibit starts with the history of taxidermy and introduces some of the more interesting pieces of historical taxidermy through the “Taxidermy Tails” pieces (kittens having tea, anyone?). Then the text covers the process of modern taxidermy and which steps to take in the field to putting the final touches on the finished product. Additionally, the 1930’s mounting of the great Australian racehorse Phar Lap, who was said “lives again through the marvels of modern taxidermy,” is covered in both text and with historic photos. The exhibit features tools and hides, eyes and mouths, and noses and forms. Several historical texts, modern catalogues, and posters were donated by Wyoming Taxidermy, and Van Dykes Taxidermy Supply, explaining the processes involved are also included. Our thanks to both of these organizations for their donations! Two views of the new taxidermy exhibit on display at the Werner Wildlife Museum. Tate Museum Geological Times 7 ? and Answers ©Drawing by Zak Pullen. Q: By Russell J. Hawley, Tate Geological Museum Education Specialist This dinosaur question is a first for me, from one of my volunteers: Which dinosaur had the greatest number of teeth? [I suspect a close tie between the hadrosaurs and ceratopsians]. – Judy Molnar, education associate Virginia Living Museum, Newport News A: You are correct – ceratopsians (horned dinosaurs) and hadrosaurs (duckbill dinosaurs) were the toothiest known dinosaurs. In both groups there were several columnar ‘tooth families’ lined up in the jaws, with a functional tooth at the crown of each column and a battery of replacement teeth stacked up below to replace the functioning tooth when it became too worn down to be useful. In general the hadrosaurs had more of these tooth families than ceratopsians – about 40 in each quadrant of the jaw on the average. In two unusually long-jawed species – Shantungosaurus giganteus from eastern China and Edmontosaurus annectens* from the western United States – there were as many as 60 of these tooth families in each quadrant. The number of spare back-up teeth in each family varied from three to six. If we assume a series of six teeth per family in one of these long-jawed species, that adds up to a total of over 1400 teeth in the animal’s mouth! But there’s a catch – what if we’re only talking about functioning teeth? At any given time, ‘only’ 240 of the hadrosaur’s teeth would be exposed for use in chewing; the rest would be buried out of sight in the bone of the jaw. That’s still a lot of teeth, but there may be a dinosaur who could give the hadrosaurs a run for their money: the wolverine-sized Pelecanimimus from the early Cretaceous of Spain. This dinosaur belonged to the ‘ostrich mimic’ group of dinosaurs, and like other members of its family would have had a long neck and long hind legs for fast running. Pelecanimimus had numerous tiny teeth set into long grooves running along the edges of the front portions of the jaws. Since the grooves were not divided into individual alveoli, and since many of the actual teeth in the only known specimen are missing, it’s hard to determine the exact number, but it was probably around 230 teeth. A close contest! Below: A pair of toothy Pelecanimimus. Skin impressions were found around the skull, indicating that there was a softtissue crest atop the rear portion of the head, and a baggy pouch under the jaw like that of a pelican (hence the name Pelecanimimus, which means ‘pelican mimic.’) There was no indication of either scales or feathers, so Pelecanimimus might have had bare skin on its head like a turkey vulture. *Unusually large, mature individuals of Edmontosaurus annectens have sometimes been misidentified as a separate species, Anatotitan copei.
