Annual Repor T 2014
Annual Report 2014 2014 Highlights Forrest Steller sea lion, Eden, gave birth to a healthy male pup on July 20, 2014. Forrest is the first male Steller sea lion born in North American collections since the 1980s. This is the second pup for parents Woody and Eden. Eleanor, “Ellie,” was born on June 20, 2013. Eider Research 2014 brought the most successful breeding season for the Eider Research Program. For the first time since the program’s start, two female Steller’s eiders naturally incubated eggs and reared ducklings. The Alaska SeaLife Center is the only facility in North America to have Steller’s eiders naturally incubate and rear their young. Sea Otter BTS Another first for the Center: Sea Otter Behind-the-Scenes (BTS) Tours were offered to guests! The Sea Otter BTS provided a unique opportunity for guests to get paw-to-paw with three playful critters. New Ticketing Counter The ticketing counter got a makeover! Guests are now greeted with a harbor-themed front desk as they enter through the doors. Chiswell Island A record number of Steller sea lion births were recorded at Chiswell Island. Alaska SeaLife Center researchers confirmed 114 births as the highest number they’ve observed since research began in 1998. Family Science Night The Education Department implemented a new program for younger children and families in Seward. “Family Science Night” offers kids and adults of all ages fun and educational activities throughout the winter. 3 and its substantial research on the hearing capabilities of arctic seals.

A New Euselachian Shark from the Early Permian of the Middle Urals, Russia
A new euselachian shark from the early Permian of the Middle Urals, Russia ALEXANDER O. IVANOV, CHRISTOPHER J. DUFFIN, and SERGE V. NAUGOLNYKH Ivanov , A.O., Duffin, C.J., and Naugolnykh, S.V. 2017. A new euselachian shark from the early Permian of the Middle Urals, Russia. Acta Palaeontologica Polonica 62 (2): 289–298. The isolated teeth of a new euselachian shark Artiodus prominens Ivanov and Duffin gen. et sp. nov. have been found in the Artinskian Stage (Early Permian) of Krasnoufimskie Klyuchiki quarry (Sverdlovsk Region, Middle Urals, Russia). The teeth of Artiodus possess a multicuspid orthodont crown with from four to nine triangular cusps; prominent labial projection terminating in a large round tubercle; distinct ornamentation from straight or recurved cristae; oval or semilu- nar, elongate, considerably vascularized base; dense vascular network formed of transverse horizontal, ascending, short secondary and semicircular canals. The teeth of the new taxon otherwise most closely resemble the teeth of some prot- acrodontid and sphenacanthid euselachians possessing a protacrodont-type crown, but differ from the teeth of all other known euselachians in the unique structure of the labial projection. The studied teeth vary in crown and base morphol- ogy, and three tooth morphotypes can be distinguished in the collection reflecting a moderate degree of linear gradient monognathic heterodonty. The range of morphologies otherwise displayed by the collection of teeth shows the greatest similarity to that described for the dentitions of relatively high-crowned hybodontids from the Mesozoic. The internal structure of the teeth, including their vascularization system is reconstructed using microtomography. The highest chon- drichthyan taxonomic diversity is found in the Artinskian, especially from the localities of the Middle and South Urals. -

Scientists Solve Mysteries of Ancient 'Shark' with Spiral-Toothed Jaw 27 February 2013
Helicoprion: Scientists solve mysteries of ancient 'shark' with spiral-toothed jaw 27 February 2013 spiral saw blade – fit into a prehistoric fish with a poor fossil record, long assumed to be a species of a shark. "New CT scans of a unique specimen from Idaho show the spiral of teeth within the jaws of the animal, giving new information on what the animal looked like, how it ate," said Leif Tapanila, principal investigator of the study, who is an ISU Associate Professor of Geosciences and Idaho Museum of Natural History division head and research curator. The results of the study, "Jaws for a spiral tooth- whorl: CT images reveal novel adaptation and phylogeny in fossil Helicoprion," are being published in the Royal Society's journal, Biology Letters. Artist conception of Helicoprion by illustrator and artist Ray Troll. (Phys.org)—Using CAT scans and making 3-D virtual reconstructions of the jaws of the ancient fish Helicoprion, Idaho State University researchers have solved some of the mysteries surrounding large spiral fossils of this fish's teeth. The ISU Museum of Natural History has the largest public collection of Helicoprion spiral-teeth fossils in the world. The fossils of this 270-million-year-old fish have long mystified scientists because, for the most part, the only remains of the fish are its teeth because its skeletal system was made of cartilage, which doesn't preserve well. No one could Leif Tapanila with two of the largest Helicoprion whorls in the world.

Abstract The California Department of Transportation (Caltrans), in cooperation with the North County Corridor Transportation Expressway Authority, proposes to construct the North County Corridor New State Route 108 in northern Stanislaus County, California. This project proposes to relocate the current alignment of SR 108 to a more southerly alignment. The California Environmental Quality Act and Caltrans guidelines require that impacts to nonrenewable paleontological resources be considered during project implementation. Therefore, a Paleontological Evaluation Report (PER) was prepared in order to determine the potential to encounter scientifically significant paleontological resources during ground-disturbing activities associated with the proposed project. The PER determined that the project area contains sediments of the Pleistocene Modesto, Riverbank, and Turlock Lake Formation as well as areas of Artificial Fill. While Artificial Fill has no paleontological sensitivity, all three Pleistocene formations have the potential to produce scientifically significant paleontological resources and therefore, have high paleontological sensitivity. Because the project area contains deposits with high paleontological sensitivity, the PER recommended that a Paleontological Mitigation Plan (PMP) be developed for the project. This preliminary PMP contains information necessary to mitigate impacts to paleontological resources during ground-disturbing activities associated with this project. It includes a discussion of area geology, the types of -
Quaternary Vertebrates of New Mexico
Vertebrate Paleontology in New Mexico. New Mexico Museum of Natural History and Science, Bulletin 2, 1993 179 QUATERNARY VERTEBRATES OF NEW MEXICO ARTHUR H. HARRIS Laboratory for Environmental Biology, University of Texas at El Paso. El Paso, TX 79968—0519 Abstract—Approximately 346 species of vertebrates are represented in the Quaternary fossil record of New Mexico. These include 4 fishes, I salamander, 13 anurans, 5 turtles, 19 lizards, 23 snakes, 119 birds, and 162 mammals. Some 22 taxa are from the vicinity of the Blancan/Irvingtonian transition, 12 most likely are Irvingtonian, and 4 are possibly Illinoian in age. Although many sites are undated with precision, most remaining sites probably are Wisconsinan, with well over 300 taxa.
