This was approved by the remain­ ing members, and the Secretary was instructed to arrange such a sym­ posium, following an outline which had been submitted by Vice-President W. D. Matthew.

It has added a new and most re­ markable type of giant quadruped, primitive stages in the evolution of the Proboscidea, Sirenia, and Cetacea, a wide variety of Hyracoidea, be­ sides Carnivora, Rodents, and, if Doctor Schlosser is correct, the earliest known Anthropoid Primates. The principal fauna is found in the Fluvio-marme beds of the Fayum district in Egypt, regarded as Upper Eocene by the Egyptian Geological Survey, but now generally accepted as Oligocene from the evidence of the marine invertebrate fauna in the underlying horizon. The marine mam­ mals and a few land mammals of doubtful affinities are found in the underlying marine formation, unquestionably of Eocene age. The Fayum fauna consists of three elements: 1. Terrestrial mammals nearly related to the Upper Eocene and Oligo­ cene fauna of Europe and North America, and whose ancestors are found in the Eocene of these countries. 2. Terrestrial mammals not related to the above, except through com­ mon derivation from the primitive Paleocene placentals, representing Downloaded from gsabulletin.gsapubs.org on February 15, 2015 Af r i c a n m a m m a l s 157 groups whose ancestors are not found in the Eocene of Europe and North America. 3. Marine mammals related to Eocene and Oligocene Cetaceans and Sirenians of Europe and North America, but in some cases more primi­ tive. The first group must be regarded as recent immigrants from the north­ ern continents. The second group may be provisionally regarded as autochthonic, evolved in Africa during the Eocene. We can not be cer­ tain that they were so because we know next to nothing of the early Ter­ tiary mammals of any part of Asia. But there are good grounds for the inference that they were not evolved in northern or north-central Asia nor in Europe, North America or South America nor Australia. The third group is presumably Mediterranean, but the presence of primitive sur­ vivals indicates perhaps that the North African coast was not the center of dispersal of these animals. Arranging the fauna thus, we have: I m m ig r a n t s A utochthones M a r in e 1. Carnivora (Hysenodonts) 1. Embrithopoda 1. Sirenla Hywnodon Arsinoitheriwn Eotherium Pterodon 2.

Apidium More than half these genera are represented by well preserved skulls; a few by a large series of skulls of several species. Great series of vertebras, limb and foot bones have been collected, but except for the marine genera there is practically no association of skull and skeleton parts, and the identification of the bones is based on considerations of size, zoological affinities, and relative abundance of the different bones and consequently Downloaded from gsabulletin.gsapubs.org on February 15, 2015 158 TEN YEARS’ PROGRESS IN VERTEBRATE PALEONTOLOGY is inexact or doubtful in most cases. The vertebrae, limb and foot bones of Arsinoitherium, vertebras and limb bones of Mceritherium, Palmomas- todon, and Ancodon, limb bones of Apterodon and Pterodon have been identified -with reasonable certainty. The remaining land mammals are known only from skulls and jaws (except Barytherium, jaws and parts of limbs). The results so far obtained are due in the first place to the work of the Egyptian Geological Survey and the British Museum; the American Mu­ seum of Natural History and the Stuttgart Museum have since secured fine collections. The earlier collections were described by Doctor Andrews in 1906; the Stuttgart and American Museum collections have not yet been fully described, but are partly known from preliminary notices. In considering the affinities of this fauna it is well to remember that Egypt is today zoologically a part of the Holarctic, not of the Ethiopian region. Its fauna includes a minority of Ethiopian genera, but is mostly related to that of southern Europe and western Asia. But in the early Tertiary the eastward extension of the Mediterranean separated Africa more or less completely from the northern world, while the Saharan desert was probably not an eeffctive barrier as it is today. Egypt was then part of an isolated Ethiopia continent, with possible Asiatic but no European connection during the early Tertiary. So much is certain from the known extent of marine formations of that period. I m m ig r a n t G r o u p Reviewing the fauna more in detail, the immigrant group includes three orders of mammals, each represented by one family. The Carnivora all belong to the Creodont family Hyasnodontidae. No modernized (Fissi- pede) carnivora are present, although these had already appeared in the European and North American Upper Eocene. The Hyaenodont genera are all Holarctic except one, which has not been found in the north, al­ though perhaps merely from lack of evidence. But the species are very distinct, and unfamiliar in adaptive type; one would conclude that the Hyaenodonts, invading a new field where they were not in competition with other families of carnivora, were expanding and modifying into new adaptations. The Artiodactyla include also but one family, the Anthracotheres, and of these only one common genus, Ancodon, with two or three species, allied to Upper Eocene and especially to early

Xinjiangchelyids provide us with great insights into the plesiomorphic anatomy of crown-cryptodires, the most diverse group of living turtles, and they are particularly relevant for understanding the origin and early divergence of the primary clades of extant turtles. Results: Exceptionally complete new xinjiangchelyid material from the ?Qigu Formation of the Turpan Basin (Xinjiang Autonomous Province, China) provides new insights into the anatomy of this group and is assigned to Xinjiangchelys wusu n. sp. A phylogenetic analysis places Xinjiangchelys wusu n. sp. in a monophyletic polytomy with other xinjiangchelyids, including Xinjiangchelys junggarensis, X. radiplicatoides, X. levensis and X. latiens. However, the analysis supports the unorthodox, though tentative placement of xinjiangchelyids and sinemydids outside of crown-group Testudines. A particularly interesting new observation is that the skull of this xinjiangchelyid retains such primitive features as a reduced interpterygoid vacuity and basipterygoid processes.

  • Constraints on the Timescale of Animal Evolutionary History
    Palaeontologia Electronica palaeo-electronica.org Constraints on the timescale of animal evolutionary history Michael J. Benton, Philip C.J. Donoghue, Robert J. Asher, Matt Friedman, Thomas J. Near, and Jakob Vinther ABSTRACT Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are fundamental to nearly every evolutionary model and process. Rates need dates. There is much debate on the most appropriate and reasonable ways in which to date the tree of life, and recent work has highlighted some confusions and complexities that can be avoided. Whether phylogenetic trees are dated after they have been estab- lished, or as part of the process of tree finding, practitioners need to know which cali- brations to use. We emphasize the importance of identifying crown (not stem) fossils, levels of confidence in their attribution to the crown, current chronostratigraphic preci- sion, the primacy of the host geological formation and asymmetric confidence intervals. Here we present calibrations for 88 key nodes across the phylogeny of animals, rang- ing from the root of Metazoa to the last common ancestor of Homo sapiens. Close attention to detail is constantly required: for example, the classic bird-mammal date (base of crown Amniota) has often been given as 310-315 Ma; the 2014 international time scale indicates a minimum age of 318 Ma.

  • Species Were Accidentally Lost,But Future Shipments Will Probably
    59.9(728) Article XXXIV.- MAMMALS FROM NICARAGUA. BY J. A. ALLEN. During the last two years the Museum has received several collections of birds and mammals from Nicaragua, made by Mr. William B. Richardson, who for many years was in the employ of Messrs. Salvin and Godman as an ornithological collector in Mexico and Central America. The mammals thus far received comprise about 400 specimens, representing nearly 60 species, of which about one-fourth appear to be undescribed. This is perhaps not surprising, in view of the fact that very few mammals have been previously received from Nicaragua. The most important of Mr. Richardson's discoveries are a new and very distinct species of Bassaricyon, and a new species of spiney rat, allied to the Ecuadorian Echimys gymnurus Thomas, and representing a hitherto unrecognized genus. The collection contains also several other species which are quite differentt from any previously known. Mr. Richardson's collecting trips have covered a wide extent of country. From his home at Matagalpa, in the central part of Nicaragua, he visited the highlands to the northward and northwestward, and also the Pacific coast; eastward his explorations extended from Lake Nicaragua to the vicinity of the Atlantic coast. The principal points at which collections were made are as follows: Matagalpa, altitude about 3000 feet. San Rafael del Norte, altitude about 5000 feet. Ocotal, altitude about 4500 feet. Chinandega, on the Pacific slope, about 700 feet. Chontales, lowlands east of Lake Nicaragua, altitude about 500 to 1000 feet. Tuma and Lavala, east of Matagalpa, on the Atlantic slope, below 1000 feet.
