MEMORIAL TO BARNUM BROWN (1873-1963) G. EDWARD LEWIS U. S. Geological Survey, Denver, Colorado Barnum Brown, the last and most successful of the great fossil hunters who led expeditions to the far corners of the earth during the Golden Age of vertebrate paleontological exploration, died on 5 February, 1963. Nothing short of a book would be adequate to do justice to this remarkable man's full life, his explora- tions, and other scientific achievements: he was associated with the American Museum of Natural History in New York from 1897 to 1963; although he did not explore the South Sea Islands, Madagas- car, or the Antipodes, he ranged far and wide over the major continents of the world and covered vast areas literally step by step. Barnum's parents were of old American stock: William Brown was a Virginian, born in 1833, who travelled westward to Wisconsin, where he married Clara Silver near Monticello, where she was born in 1840. They loaded their possessions into an ox-drawn covered wagon in 1859 and headed westward with their first child, Clara Melissa. They averaged 10 miles a day on the way to Kansas Territory where, near Lickskillet in Osage County, a second daughter, Alice Elizabeth, was born on 4 January 1860. Nearby in the same county was a place underlain by coal where they built a one-room cabin on Carbon Hill, to the west of which Carbondale sprang up some years later. The cabin doors were closed by flaps of canvas; the windows were covered with greased paper; there were cots, packing boxes, and barrel chairs for furniture. -

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). -

Raptors in Action 1 Suggested Pre-Visit Activities
PROGRAM OVERVIEW TOPIC: Small theropods commonly known as “raptors.” THEME: Explore the adaptations that made raptors unique and successful, like claws, intelligence, vision, speed, and hollow bones. PROGRAM DESCRIPTION: Razor-sharp teeth and sickle-like claws are just a few of the characteristics that have made raptors famous. Working in groups, students will build a working model of a raptor leg and then bring it to life while competing in a relay race that simulates the hunting techniques of these carnivorous animals. AUDIENCE: Grades 3–6 CURRICULUM CONNECTIONS: Grade 3 Science: Building with a Variety of Materials Grade 3–6 Math: Patterns and Relations Grade 4 Science: Building Devices and Vehicles that Move Grade 6 Science: Evidence and Investigation PROGRAM ObJECTIVES: 1. Students will understand the adaptations that contributed to the success of small theropods. 2. Students will explore the function of the muscles used in vertebrate movement and the mechanics of how a raptor leg works. 3. Students will understand the function of the raptorial claw. 4. Students will discover connections between small theropod dinosaurs and birds. SUGGESTED PRE-VISIT ACTIVITIES UNDERstANDING CLADIstICS Animals and plants are often referred to as part of a family or group. For example, the dog is part of the canine family (along with wolves, coyotes, foxes, etc.). Scientists group living things together based on relationships to gain insight into where they came from. This helps us identify common ancestors of different organisms. This method of grouping is called “cladistics.” Cladistics is a system that uses branches like a family tree to show how organisms are related to one another. -

Jurassic Park Connecticut Valley
JURASSIC PARK is in the CONNECTICUT VALLEY Meet Dr. Robert T. Bakker Saturday, November 19 who will sign books Talks and Book Signings at 11 a.m. and 2 p.m. and talk at Dinosaur State Park World-renowned paleontologist and author, Dr. Robert Bakker, will be at the park on Saturday, November 19, 2016. He will give two talks: at 11 a.m. and at 2 p.m. He will also be available to sign books. Bakker was a student at Yale working with Dr. John Ostrom when the tracks were discovered 50 years ago. He will be able to offer a unique perspective on what that was like as well as discuss his own work. The bookstore will have copies of his novel, “Raptor Red,” and several of his children’s books for sale including his newest book, “The Big Golden Book of Dinosaurs,” which is illustrated by the famous paleo artist Luis A. Rey. Bakker is probably most famous for his book, “The Dinosaur Heresies,” published in 1986. He helped reshape modern theories about dinosaurs, particularly by adding support to the theory that some dinosaurs were endothermic (warm-blooded). He earned a B.A. from Yale University and a Ph.D. from Harvard University. Along with his mentor at Yale, John Ostrom, Bakker was responsible for initiating the ongoing “dinosaur renaissance” in paleontological studies, beginning with Bakker’s article “Dinosaur Renaissance” in the April 1975 issue of Scientific American. His special field is the ecological context and behavior of dinosaurs. Bakker has been a major proponent of the theory that dinosaurs were active, intelligent and adaptable. -
OF the SKELETON.' by HENRY FAIRFIELD OSBORN
56.81.9T Article IV.- TYRANNOSAURUS, RESTORATION AND MODEL OF THE SKELETON.' By HENRY FAIRFIELD OSBORN. PLATES IV-VI. In three previous contributions2 the structure of Tyrannosaurus has been partly described; in the present paper a restoration model is published; it is based on the two skeletons secured by Mr. Barnum Brown in the Upper Cretaceous of Montana. The mounting of these two skeletons presents mechanical problems of very great difficulty. The size and weight of the various parts are enormous. The height of the head in the standing position reaches from 18 to 20 feet above the ground; the knee joint alone reaches 6 feet above the ground. All the bones are massive; the pelvis, femur and skull are extremely heavy. Experience with Brontosacurus and with other large dinosaurs proves that it is impossible to design a metallic frame in the right pose in advance of assembling the parts. Even a scale restoration model of the animal as a whole does not obviate the difficulty. Accordingly in preparing to mount Tyrannosaurus for exhibition a new method has been adopted, namely, to prepare a scale model of every bone in the skeleton and mount this small skeleton with flexible joints and parts so that all studies and experiments as to pose can be made with the models. This difficult and delicate undertaking was entrusted to Mr. Erwin Christman of the artistic staff of the Department of Vertebrate Palke- ontology of the Museum, who has prepared two very exact models to a one-sixth scale, representing our two skeletons of Tyrannosaurus rex, which fortunately are of exactly the same size. -
Dinosaur Provincial Park, One of the Greatest Outdoor Laboratories for Understanding Late Cretaceous Ecosystems Philip J
Dinosaur Provincial Park, One of the Greatest Outdoor Laboratories for Understanding Late Cretaceous Ecosystems Philip J. Currie University of Alberta, Edmonton, Alberta [email protected] Dinosaur Provincial Park (Alberta, Canada) is arguably one of the best, if not the best, Late Cretaceous terrestrial ecosystems known. The Campanian rocks of the Park are part of an almost continuous succession of rocks along the Red Deer River, covering the last ten million years of the history of non-avian dinosaurs. Three formations (two terrestrial and one marine) are recognized in Dinosaur Provincial Park, and each has its own distinctive fauna. The majority of dinosaurs are recovered from the sandstones, siltstones and mudstones of the Dinosaur Park Formation, which is up to sixty metres in thickness. Radiometric dates indicate that the formation was deposited from 76.5 to 74.8 million years. In 1889, T.C. Weston of the Geological Survey of Canada discovered the first professionally recorded fossils in what is now the Park. He reported the presence of vast quantities of bones, but had no time to make any significant collections. On the basis of his reports, Lawrence M. Lambe of the same organization led his first expedition to the region eight years later. Numerous specimens were recovered over three field seasons, and led soon after to the description of the first dinosaur species from Canada. By 1912, field parties led by Barnum Brown of the American Museum of Natural History (New York) had moved into the region, recognizing the richness of the area. However, Brown was soon competing with the Sternberg family and other collectors, who recovered hundreds of dinosaur skeletons that eventually found homes in more than 25 public institutions around the world. -
Possible Evidence of Gregarious Behavior in Tyrannosaurids
GAIA N'15, LlSBOAlLISBON, DEZEMBRO/DECEMBER 1998, pp. 271-277 (ISSN: 0871-5424) POSSIBLE EVIDENCE OF GREGARIOUS BEHAVIOR IN TYRANNOSAURIDS Philip J. CURRIE Royal Tyrrell Museum of Palaeontology. Box 7500 Drumheller, ALBERTA TOJ OYO. CANADA ABSTRACT: In 1910, a collecting party from the American Museum of Natural History led by Barnum Brown floated down the Red Deer Riverof Alberta. In the Horseshoe Canyon Forma tion (Edmonton Group, Campanian-Maastrichtian, Upper Cretaceous) close to the mouth of Big Valley Creek, they excavated semi-articulated skeletons of several individuals of Alber tosaurus sarcophagus OSBORN, 1905 from a single quarry. Other than the tyrannosaurids, only two hadrosaur phalanges were recovered. Eight articulated feet with associated limb bones were given catalogue numbers, as was an articulated string oftwenty-five caudal ver tebrae_ The remaining tyrannosaurid fossils that could not be associated with any of these specimens or with each other were all assigned a single number. Brown's other discoveries of well-preserved dinosaur skeletons in southern Alberta overshadowed the tyrannosaurid find, and the specimens were largely forgotten. However, it is the best evidence that exists to suggest that tyrannosaurids may have been gregarious animals. The almost complete lack of herbivore bones from the excavation suggests that this was probably not a predator trap, such as has been postulated for the Allosaurus MARSH, 1877 accumulation at the Cleveland-Lloyd Quarry near Price, Utah. Comparative measurements indicate that juvenile tyrannosaurids were probably almost as fast at running as ornithomimids. This suggests a division of labor amongst a hunting pack of tyrannosaurids.
