  • A Census of Dinosaur Fossils Recovered from the Hell Creek and Lance Formations (Maastrichtian)
    The Journal of Paleontological Sciences: JPS.C.2019.01 1 TAKING COUNT: A Census of Dinosaur Fossils Recovered From the Hell Creek and Lance Formations (Maastrichtian). ______________________________________________________________________________________ Walter W. Stein- President, PaleoAdventures 1432 Mill St.. Belle Fourche, SD 57717. [email protected] 605-210-1275 ABSTRACT: A census of Hell Creek and Lance Formation dinosaur remains was conducted from April, 2017 through February of 2018. Online databases were reviewed and curators and collections managers interviewed in an effort to determine how much material had been collected over the past 130+ years of exploration. The results of this new census has led to numerous observations regarding the quantity, quality, and locations of the total collection, as well as ancillary data on the faunal diversity and density of Late Cretaceous dinosaur populations. By reviewing the available data, it was also possible to make general observations regarding the current state of certain exploration programs, the nature of collection bias present in those collections and the availability of today's online databases. A total of 653 distinct, associated and/or articulated remains (skulls and partial skeletons) were located. Ceratopsid skulls and partial skeletons (mostly identified as Triceratops) were the most numerous, tallying over 335+ specimens. Hadrosaurids (Edmontosaurus) were second with at least 149 associated and/or articulated remains. Tyrannosaurids (Tyrannosaurus and Nanotyrannus) were third with a total of 71 associated and/or articulated specimens currently known to exist. Basal ornithopods (Thescelosaurus) were also well represented by at least 42 known associated and/or articulated remains. The remaining associated and/or articulated specimens, included pachycephalosaurids (18), ankylosaurids (6) nodosaurids (6), ornithomimids (13), oviraptorosaurids (9), dromaeosaurids (1) and troodontids (1).

  • Tyrannosaurus Sue a Letter from Bruce Adolphe
    Tyrannosaurus Sue A letter from Bruce Adolphe Humans, like you, have the amazing ability to think about the past. Not only can we think about what we had for dinner last night or recall a concert or sports event from last year, we can even think about things that happened before we were born — or before anyone was born. Like thinking about dinosaurs. Because paleontologists (scientists who study fossils and remains from millions of years ago) can uncover the past for us, we can look at dinosaur bones and think about what life was like 67 million years ago. That’s way before smart phones. It’s even before umbrellas. In fact, it is before people existed! In the year 2000, the most complete set of dinosaur bones ever discovered was put on display at the Field Museum of Natural History in Chicago. The bones belonged to a Tyrannosaurus rex that weighed about seven tons (when alive), and it had 60 teeth, some as long as 12 inches. Because the T. rex was discovered by a paleontologist named Sue Hendrickson, we call the dinosaur Sue. Its official name is FMNH PR 2081. “Sue” is catchier, I think you will agree. When “Sue” was put on display for the first time, the Chicago Chamber Musicians were invited to play a concert in the museum to celebrate the day, and they asked me to compose them a piece about the dinosaur. That’s why we have the piece Tyrannosaurus Sue. If you were writing a piece of music about a Tyrannosaurus rex, which one of these instruments would you choose to portray the huge dinosaur: flute; trombone; violin; cello; clarinet.

  • 2006 Flag Report on 11 Expeditions
    In 2005, Wings WorldQuest launched the Wings Expedition Flag Program to bring visibility and support to women leading expeditions of discovery. The Flag promotes the organization’s dedication to advancing exploration in science and art for educational purposes. The 2005 Flag Report, documenting six expeditions, was distributed to hundreds of young people across the country. We are delighted to bring you the 2006 Flag Report on 11 expeditions. A dozen more are currently in the field. The expeditions in the 2006 Flag Report cover the depths of the ocean, the grasslands of India, the Gobi desert, caves in Honduras and the Bahamas, jungles of Central America and the glaciers of the American Northwest. The explorers shed new light on mysteries of ancient humans as well as mysteries about Mars. They discovered new species, worked to save imperiled species, and extended their reach across cultural divides. What unites them is their passion for learning, their commitment to sharing their dis- coveries and their dedication to the preservation of the fragile zones they are exploring. • Kate Harris bicycled 4000 km as she traced Marco Polo’s travels along the ancient Silk Road. • Genie Clark recorded discoveries about coral reef fish in the Solomon Islands. • Sue Hendrickson searched for dinosaur fossils in Wyoming and explored caves in Honduras to find new species of geckos. • Stephanie Schwabe dived into forbidding caves in the Bahamas to examine the role that microbes play in the earth’s chemistry. • Gitanjali Banerjee investigated the endangered greater one-horned rhino in Jaldapara Wildlife Sanctuary, India. • Edith Widder, using her remarkable infrared camera invention Eye in the Sea, found new species on the ocean floor.

  • The Ligamental Scar in the Costovertebral Articulation of the Tyrannosaurid Dinosaurs
    The ligamental scar in the costovertebral articulation of the tyrannosaurid dinosaurs TATSUYA HIRASAWA Hirasawa, T. 2009. The ligamental scar in the costovertebral articulation of the tyrannosaurid dinosaurs. Acta Palaeonto− logica Polonica 54 (1): 49–59. The costovertebral articulation is integral to constrain the thoracic kinematics and to infer the breathing mechanism in the respect with costal aspiration. However, the structure of the costovertebral articulation in non−avian theropods has not been studied in great detail before. This study highlights the Tyrannosauridae, which is represented by numerous com− plete specimens. Costovertebral articulations of ten tyrannosaurid specimens, including two nearly in−situ articulated fos− sils, were investigated and compared with those in extant Archosauria. For extant archosaurs, dissections were conducted to rationalize the soft tissue anatomy in tyrannosaurids. This study shows that the rib articulates ventrally or postero− ventrally with the distal end of the corresponding vertebral transverse process in the tyrannosaurid ribcage. A ligament (ligamentum costotransversarium) can be reconstructed to connect the rib tuberculum to the transverse process in each ar− ticulation. The scar for lig. costotransversarium is recognizable in many theropod skeletons, and this rugosity can be used to identify the rotational axis for the rib. This result provides a cornerstone for exploring the evolution of the ribcage and breathing mechanisms across the theropod lineage leading to birds. Key words: Dinosauria, Theropoda, Tyrannosauridae, ribcage, vertebra, rib, soft tissue anatomy.

  • The Story of Sue the T-Rex and Controversy Over Access to Fossils
    HPLS (2020) 42:2 https://doi.org/10.1007/s40656-019-0288-4 ORIGINAL PAPER Assumptions of authority: the story of Sue the T‑rex and controversy over access to fossils Elizabeth D. Jones1,2 Received: 26 October 2018 / Accepted: 11 October 2019 © The Author(s) 2019 Abstract Although the buying, selling, and trading of fossils has been a princi- ple part of paleontological practice over the centuries, the commercial collection of fossils today has re-emerged into a pervasive and lucrative industry. In the United States, the number of commercial companies driving the legal, and sometimes ille- gal, selling of fossils is estimated to have doubled since the 1980s, and worries from academic paleontologists over this issue has increased accordingly. Indeed, some view the commercialization of fossils as one of the greatest threats to paleontology today. In this article, I address the story of “Sue”—the largest, most complete, and most expensive Tyrannosaurus rex ever excavated—whose discovery incited a series of high-profle legal battles throughout the 1990s over the question of “Who owns Sue?” Over the course of a decade, various stakeholders from academic paleontolo- gists and fossil dealers to Native Americans, private citizens, and government of- cials all laid claim to Sue. In exploring this case, I argue that assumptions of author- ity are responsible for initiating and sustaining debates over fossil access. Here, assumptions of authority are understood as assumptions of ownership, or expertise, or in some cases both. Viewing the story from this perspective illuminates the sig- nifcance of fossils as boundary objects. It also highlights the process of boundary- work by which individuals and groups constructed or deconstructed borders around Sue (specifcally) and fossil access (more generally) to establish their own authority.

INTRODUCTION In August 1990, commercial fossil hunters from the Black Hills Geologic Institute (“Black Hills”) discovered the remains of an almost-complete Tyrannosaurus Rex skeleton located in the badlands of South Dakota.1 Named “Sue” after her discoverer,2 the fossil immediately became the subject of controversy. Although many of the facts were disputed, the collectors gave the purported owner of the land, a Native American rancher named Maurice Williams, a check for $5,000, which he cashed, and the collectors excavated Sue.3 The fair market value of a T-Rex skeleton with that degree of completeness was over eight million dollars.4 Once the discovery began to garner publicity, Williams began a fierce court battle to rescind the contract with Black Hills, claiming that the $5,000 was merely a payment * Assistant Professor of Law, Cumberland School of Law, Samford University; B.A., 1996, Dartmouth College; J.D., 1999, Harvard Law School.
