This small form displays a striking selenolophodont morphology associated with a mixture of primitive “condylar- thran” dental characters and derived tapiromorph features. Skopaiolophus is here tentatively referred to a group of Asian tapiromorphs unknown so far. The occurrence of such a form in Pondaung suggests that primitive tapiromorphs might have persisted in southeast Asia until the late middle Eocene while they became extinct elsewhere in both Eurasia and North America. © 2006 Elsevier SAS.

One of the three founders of the science of vertebrate paleon- tology in America, his career furnishes an outstanding exatnple of the indomitable spirit that drives men on to a determined goal. His motto might well have been. "\l.That 1 have, I hold." He asked no quarter, and gave none. :It home around a camp fire or in an army tent, formal as a presiding officer or in society, at times austere and autocratic, at others a raconteur of note, he left a lasting impression on his chosen 111-anch of science. Summarizing his work statistically, it may be said that he- tween 1861 and 1899 he published about 300 papers, reports, and books. Of new genera he described 225, and of new species, 496; of new families 64, of su1)orders 8, of orders 19, and of subclasses I. Of his work on vertebrate fossils in general, Osbom says that he "carried out the most intensive field esl)loration known to science ant1 pul~lishetl a large num1)er of 1)reliminary papcrs, which fairly revol~~tionizedour knowledge."

Article XXXVIII. -NOTE on SOME WORM (?) BUR- ROWS in ROCKS of the CHEMUNG GROUP of NEW YORK
Article XXXVIII. -NOTE ON SOME WORM (?) BUR- ROWS IN ROCKS OF THE CHEMUNG GROUP OF NEW YORK. By R. P. WHITFIELD. Arenicolites chemungensis, sp. nov. PLATE XIV, FIGS. I AND 2. While working up the fossils of the Potsdam sandstone for the Wisconsin Report, in I876 and I877, there came into my hands a number of specimens representing the so-called Scolithus, which I described as Arenicolites woodi in Volume IV of Prof. T. C. Chamberlain's Report of I882. One block of that series showed the original surface of the mud-covered sandstone with the burrows of the worm (?) which made the perforations, together with the little hillocks surrounding the outlet of the burrows, just as the animal built them up by its castings during life; proving pretty conclusively that it must have been a marine worm-like animal which caused the perforations. Among the geological specimens of the Chemung Group in the Museum, from near Bath, Steuben Co., New York, I find an example so nearly resembling that figured in the Wis- consin Report above referred to, that there can be no ques- tion as to the similarity of its origin. On this Chemung specimen the hillocks are somewhat larger and the funnels more distinct, being generally 5 or 6 mm. in diameter, and the walls surrounding them about 2 mm. thick, while some of the hillocks are much larger and higher and appear to have collapsed from the semifluidity of the sand, closing up the top of the burrow so as to show a mere slit in its place. -

New Early Eocene Basal Tapiromorph from Southern China and Its Phylogenetic Implications
New Early Eocene Basal tapiromorph from Southern China and Its Phylogenetic Implications Bin Bai1,2*, Yuanqing Wang1*, Jin Meng2,1, Qian Li1, Xun Jin1 1 Key Laboratory of Vertebrate Evolution and Human Origins of Chinese Academy of Sciences, Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, Beijing, China, 2 Division of Paleontology, American Museum of Natural History, New York, New York, United States of America Abstract A new Early Eocene tapiromorph, Meridiolophus expansus gen. et sp. nov., from the Sanshui Basin, Guangdong Province, China, is described and discussed. It is the first reported Eocene mammal from the basin. The new taxon, represented by a left fragmentary mandible, is characterized by an expanded anterior symphyseal region, a long diastema between c1 and p1, a rather short diastema between p1 and p2, smaller premolars relative to molars, an incipient metaconid appressed to the protoconid on p3, a prominent entoconid on p4, molar metaconid not twinned, cristid obliqua extending mesially and slightly lingually from the hypoconid, inclined metalophid and hypolophid, and small hypoconulid on the lower preultimate molars. Meridiolophus is morphologically intermediate between basal Homogalax-like taxa and derived tapiromorphs (such as Heptodon). Phylogenetic analysis indicates Equidae is more closely related to Tapiromorpha than to Palaeotheriidae, although the latter is only represented by a single species Pachynolophus eulaliensis. ‘Isectolophidae’, with exception of Meridiolophus and Karagalax, has the closest affinity with Chalicotherioidea. Furthermore, the majority rule consensus tree shows that Meridiolophus is closer to Karagalax than to any other ‘isectolophid’, and both genera represent stem taxa to crown group Ceratomorpha.

Furry Folk: Synapsids and Mammals
FURRY FOLK: SYNAPSIDS AND MAMMALS Of all the great transitions between major structural grades within vertebrates, the transition from basal amniotes to basal mammals is represented by the most complete and continuous fossil record, extending from the Middle Pennsylvanian to the Late Triassic and spanning some 75 to 100 million years. —James Hopson, “Synapsid evolution and the radiation of non-eutherian mammals,” 1994 At the very beginning of their history, amniotes split into two lineages, the synapsids and the reptiles. Traditionally, the earliest synapsids have been called the “mammal-like reptiles,” but this is a misnomer. The earliest synapsids had nothing to do with reptiles as the term is normally used (referring to the living reptiles and their extinct relatives). Early synapsids are “reptilian” only in the sense that they initially retained a lot of primitive amniote characters. Part of the reason for the persistence of this archaic usage is the precladistic view that the synapsids are descended from “anapsid” reptiles, so they are also reptiles. In fact, a lot of the “anapsids” of the Carboniferous, such as Hylonomus, which once had been postulated as ancestral to synapsids, are actually derived members of the diapsids (Gauthier, 1994). Furthermore, the earliest reptiles (Westlothiana from the Early Carboniferous) and the earliest synapsids (Protoclepsydrops from the Early Carboniferous and Archaeothyris from the Middle Carboniferous) are equally ancient, showing that their lineages diverged at the beginning of the Carboniferous, rather than synapsids evolving from the “anapsids.” For all these reasons, it is no longer appropriate to use the term “mammal-like reptiles.” If one must use a nontaxonomic term, “protomammals” is a alternative with no misleading phylogenetic implications. -

OVERVIEW OF MAMMALIAN BIOSTRATIGRAPHY IN THE PALEOCENE-EOCENE FORT UNION AND WILLWOOD FORMATIONS OF THE BIGHORN AND CLARKS FORK BASINS PHILIPD. GINGERICH~and WILLIAMC. CLYDE^ 1Department of Geological Sciences and Museum of Paleontology, The University of Michigan, Ann Arbor, Michigan 48109-1079 2Department of Earth Sciences, University of New Hampshire, Durham, New Hampshire 03824-3589 Abstract. -Some 2200 fossil vertebrate localities are known from the Paleocene Fort Union Formation and from the Paleocene and lower Eocene Willwood Formation of the Bighorn and Clarks Fork basins in northwestern Wyoming. Many localities yield faunas adequate to enable reference to one of the twenty distinct land-mammal zones representing the Puercan, Torrejonian, Tiffanian, Clarkforkian, and Wasatchian land-mammal ages spanning Paleo- cene and early Eocene time here. These are grouped biostratigraphically and plotted on a map of the two basins combined. Range charts of mammalian genera are compared for (1) the Polecat Bench-Sand Coulee area in the Clarks Fork and northern Bighorn basins, (2) the Foster Gulch-McCullough Peaks area in the northern Bighorn Basin, (3) the central Bighorn Basin, and (4) the southern Bighorn Basin. These show that mammalian biostratigraphy is similar in all four areas, with parts of the stratigraphic record being better developed in some areas than in others. The Paleocene and earliest Eocene are best known from the Clarks Fork Basin and from the northern Bighorn Basin, whereas middle and late early Eocene faunas are principally known from the west side of the northern and central parts of the Bighorn Basin. East-west asymmetry in the distribution of mammalian faunas reflects overthrusting from the west as strata and their contained fossil faunas accumulated and were buried.
