- ItemAn aboriginal rock alignment in the Toiyabe Range, central Nevada. American Museum novitates ; no. 2534(New York, N.Y. : American Museum of Natural History, 1974) Thomas, David Hurst.; McKee, Edwin H."Two unusual rock walls in end-to-end alignment situated southeast of Austin, Lander County, Nevada, are described and their possible origin and use discussed. The eastern wall, about 300 feet long, extends from a canyon bottom, up a moderately steep hillside, and terminates just short of cliffy outcrops about two-thirds of the way to the ridge crest. The western wall, approximately 200 feet long, runs about halfway up the opposite side of the ridge. Judging from the type of projectile points found nearby, the walls are tentatively dated to the Reveille or the Underdown phases of the local archeological sequence (i.e., ca. 1000 BC to AD 1300). Several alternative hypotheses are considered to explain this feature, probably the best of which is that the rock barriers are prehistoric hunting fences, constructed to ambush deer or antelope"--P. [1].

- ItemAcleistochelys, a new side-necked turtle (Pelomedusoides, Bothremydidae) from the Paleocene of Mali ; American Museum novitates, no. 3549(New York, NY : American Museum of Natural History, 2007) Gaffney, Eugene S.; Roberts, Eric (Eric M.); Sissoko, Famory.; Bouaré, Mohamed L.; Tapanila, Leif Michael.; O'Leary, Maureen A.The Paleocene Teberemt Formation south of the Adrar des Iforas Mountains, between Saguirilidad and In Fargas, Mali, yielded a nearly complete skull of a new genus and species of side-necked turtle, Acleistochelys maliensis. Acleistochelys is a member of the family Bothremydidae Baur, 1891, because: (1) the fossa precolumellaris is absent, (2) the foramen stapedio-temporale faces anteriorly, (3) the eustachian tube is separated from the stapes by bone, and (4) an exoccipital-quadrate contact is present. Within the Bothremydidae, Acleistochelys belongs to the tribe Taphrosphyini because: (1) the maxilla-quadratojugal contact is absent, (2) the palate is dorsally arched, (3) there is only a small contribution of the palatine to the triturating surfaces, and (4) the septum orbitotemporale is at least partially open. Acleistochelys is most closely related to Azabbaremys because both share a narrow vomer lacking a posterior attachment to the palatines. The specimen was found in a marine limestone associated with crocodiles, echinoids, and mollusks.

- ItemAcroplous vorax Hotton (Amphibia, Saurerpetontidae) restudied in light of new material. American Museum novitates ; no. 2662(New York, N.Y. : American Museum of Natural History, 1978) Coldiron, Ronn W."A new individual of Acroplous vorax is described and its systematic position within the Saurerpetonidae is reexamined. The new specimen is clearly conspecific with the type as shown by the narrow midline elements, broad supratemporal and intertemporal, wide but short lacrimal, and nearly identical pterygoids. The new specimen offers more data on the braincase, pterygoid occiput, lower jaw, and humerus. The internal process of the pterygoid is small and a well-developed epipterygoid caps the dorsal process of the pterygoid, indicating a more primitive basal articulation than that interpreted for Isodectes. Unfortunately, the condition in Saurerpeton is unknown for comparison. Like all other saurerpetonid genera (Dvinosuarus, Saurerpeton, Isodectes) the lower jaw has a large symphysial tusk and a long retroarticular process. The new material, however, is primitive in having a small posterior meckelian fossa. Advanced lower jaw characters are an overall dorsoventral compression and a unique wide exposure of the articular both laterally and medially. The vertebrae are unique among saurerpetontids in having a cartilaginous portion of pleurocentrum conspicuously larger than the intercentrum. A hypothesis of relationships suggests Acroplous to be the sister group of Isodectes and brachyopids. As a result the saurerpetontids are paraphyletic since they exclude the brachyopids. Further, if brachyopids are the sister group to 'saurerpetontids' and other stereospondyls are more closely related to eryopids, then stereospondyls would be diphyletic. There are many characters, however, that contradict the hypothesis of stereospondyls being diphyletic. Dvinosaurus, long thought to be an aberrant member of the trimerorhachoids, is thought to be the sister group to 'saurerpetontids' and brachyopids"--P. [1].
- ItemAcropyga and Azteca ants (Hymenoptera, Formicidae) with scale insects (Sternorrhyncha, Coccoidea) : 20 million years of symbiosis. American Museum novitates ; no. 3335(New York, NY : American Museum of Natural History, 2001) Johnson, Christine (Entomologist); Agosti, Donat.; Delabie, Jacques H. C.; Dumpert, Klaus.; Williams, D. J. (Douglas John); Tschirnhaus, Michael von.; Maschwitz, Ulrich.Species of the genus Acropyga are rarely encountered subterranean ants that rely on mealybugs or aphids to provide their nutritional needs. Female Acropyga (Formicinae) alates of pantropical and Mediterranean species carry mealybugs with their mandibles while swarming and probably inoculate their new nests with these mealybugs. The natural history of Acropyga and other mealybug-tending ant species, a summary of the various reports of Acropyga females toting mealybugs, and a new record from French Guiana are presented here. Also provided are a first report and description of Acropyga alates with mealybugs in Dominican amber dated to the Miocene, a discovery indicating that this intimate association and relatively uncommon behavior has existed for at least 15-20 million years. The mealybugs found with the Acropyga females in amber are related to the hypogaeic genera Eumyrmococcus Silvestri and Neochavesia Williams & Granara de Willink (Pseudococcidae, Rhizoecinae) and represent three new species of a new genus. The genus Electromyrmococcus and the species Electromyrmococcus abductus Williams, Electromyrmococcus inclusus Williams and Agosti, and Electromyrmococcus reginae Williams are described. A piece of Dominican amber containing workers of Azteca alpha Wilson (Dolichoderinae) and 23 scale insects is also presented and the significance of these specimens in Dominican amber is discussed.
- ItemAdaptations for egg eating in the snake Elaphe climacophora (Boie). American Museum novitates ; no. 1571(New York : American Museum of Natural History, 1952) Gans, Carl, 1923-; Oshima, Masamitsu, 1884-1965."This paper describes the habits and vertebral modifications for egg crushing of a species of Elaphe specialized for the eating of eggs. It is pointed out that considerable variation exists among the three specimens examined, and thus a final decision as to the cause and significance of this variation is precluded at the present time by lack of material, but a number of hypotheses are offered to explain the evolutionary significance of the vertebral modification. There are possible taxonomic implications in view of the development of similar specialization among related forms and their bearing on the status of the snakes (Dasypeltinae), now placed in a separate subfamily largely because of similar but more extreme adaptive specialization. It may be of interest to note here that preliminary investigations of the senior author show that similar specialization exists in Elaphe carinata, E. dione, and E. schrencki anomala, among Chinese species of Elaphe examined thus far. In E. carinata modification of the hypapophyses has progressed to the point of penetration of the esophagus"--P. 14-15.
