• The Expedition to the Miocene of Western Nebraska, and Agate Springs, 1919, by Albert Thomson. Thomson and George Olsen left New York on June 15. They visited several museums on the way and arrived June 20th at Agate, NE. They immediately began work at the old quarry to secure a slab of Diceratherium for exhibition. The slab measures about 4 feet in width, 8 feet in length and about 14 inches in depth. It weights about 3 tons. Thomson and Olsen spent 2 months in getting it out of the quarry and preparing it for transportation. They then spent 2 months in the quarry Mr. Barner opened up in 1917 in hope of finding some Dinohyus material, but no success. The last 2 weeks were spent in prospecting in the beds of the Niobrara River not far from the quarry. They obtained 3 Daimonelix, small but good examples, and a skull and partial skeleton of Merychus, also some Oxydactylus bones. Other Field Work, taken from W. D. Matthew's report for 1919. In the early part of the year Barnum Brown investigated a number of prospects in Oklahoma and northern Texas. In November Mr. H. E. Anthony, assisted by Mr. Charles Falkenbach, undertook an expedition for living and extinct mammals to the island of Jamaica. Mr. Anthony had already secured large and interesting collections from Porto Rico and Cuba. Preliminary reports from Mr. Anthony led them to believe that he has found good fossil deposit. Purchases, 1919. A partial skeleton of a small pterosaur from the Cretaceous chalk beds of Kansas was purchased from Mr. C. H. Sternberg. Also from Mr. Sternberg is the hind half of a skeleton of the extinct bear, Arctotherium, from Rock Creek beds of Texas.
