On the Geology of the Western States of North America, 0000, Owen David Dale,
The remarks here submitted will be confined chiefly to that part of the Western States of North America watered by the rivers Ohio, Wabash, Illinois, Rock, Wisconsin, Cumberland and Tennessee, lying between the 35th and 43rd degree of N. latitude and the 81st and 91st of W. longitude. The district includes the states of Illinois, Indiana, Ohio, Kentucky, Tennessee, and the Du Buque and Mineral Point districts of Iowa and Wisconsin. This territory occupies an area of about half a million of square miles, but its geological features are remarkably uniform, belonging, with a few partial exceptions, to the periods of the bituminous coal and carboniferous limestone as found in Europe, and the Silurian rocks as described by Sir R. Murchison; the exceptions are the superficial deposits which occasionally cover up these from view over considerable tracts, and these must either be referred to the age of gigantic mammalia and formations of a much newer date, or belong to a marl and greensand found in the western district of Tennessee, probably a portion of the greensand and other members of the cretaceous group. A general idea of the geological formations of the whole tract may be obtained from the annexed diagram. ... This 250-word extract was created in the absence of an abstract

The Discovery, Exploration and Scientific Investigation of the Wellington Caves, New South Wales, 1963, Lane Edward A. , Richards Aola M.

Although research has been unable to establish a definite date of discovery for the limestone caves at Wellington, New South Wales, documentary evidence has placed it as 1828. The actual discovery could have been made earlier by soldiers or convicts from the Wellington Settlement, which dated from 1823. Whether the aborigines knew of the cave's existence before 1828 is uncertain, but likely, as in 1830 they referred to them as "Mulwang". A number of very small limestone caves were also discovered about the same time in the nearby Molong area. The Bungonia Caves, in the Marulan district near Goulburn, were first written about a short time later. On all the evidence available at present, the Wellington Caves can be considered to be the first of any size discovered on the mainland of Australia. The Wellington Caves are situated in a low, limestone outcrop about six miles south by road from the present town of Wellington, and approximately 190 miles west-north-west of Sydney. They are at an altitude of 1000 feet, about half a mile from the present bed of the Bell River, a tributary of the Macquarie River. One large cave and several small caves exist in the outcrop, and range in size from simple shafts to passages 200 to 300 feet long. Mining for phosphate has been carried out, resulting in extensive galleries, often unstable, at several levels. Two caves have been lit by electricity for the tourist trades; the Cathedral Cave, 400 feet long, maximum width 100 feet, and up to 50 feet high; and the smaller Gaden Cave. The Cathedral Cave contains what is believed to be the largest stalagmite in the world, "The Altar", which stands on a flat floor, is 100 feet round the base and almost touches the roof about 40 feet above. It appears that the name Cathedral was not applied to the cave until this century. The original names were "The Great Cave", "The Large Cave" or "The Main Cave". The Altar was named by Thomas Mitchell in 1830. See map of cave and Plate. Extensive Pleistocene bone deposits - a veritable mine of bone fragments - were found in 1830, and have been studied by palaeontologists almost continually ever since. These bone deposits introduced to the world the extinct marsupials of Australia, and have a special importance in view of the peculiar features of the living fauna of the continent. The names of many famous explorers and scientists are associated with this history, among the most prominent being Sir Thomas Mitchell and Sir Richard Owen. Anderson (1933) gives a brief outline of why the Wellington Caves fossil bone beds so rapidly attracted world-wide interest. During the 18th and early 19th Century, the great palaeontologist, Baron Georges Cuvier, and others, supposed that the earth had suffered a series of catastrophic changes in prehistoric times. As a result of each of these, the animals living in a certain area were destroyed, the area being repopulated from isolated portions of the earth that had escaped the catastrophe. The Bilical Deluge was believed to have been the most recent. Darwin, during the voyage of the Beagle around the world (1832-37), was struck by the abundance of Pleistocene mammalian fossils in South America, and also by the fact that, while these differed from living forms, and were in part of gigantic dimensions, they were closely related to present-day forms in that continent. Darwin's theory of descent with modification did not reconcile with the ideas of Cuvier and others. As the living mammalian fauna of Australia was even more distinctive than that of South America, it was a matter of importance and excitement to discover the nature of the mammals which had lived in Australia in the late Tertiary and Pleistocene.


Contribution to the study of the biology of Asellus cavaticus Leydig (preliminary note)., 1965, Henry Jean Paul
The cavernicole asellid Asellus cavaticus Leydig has been reared in our laboratory for more than twenty months, permitting us to give some data on the sexual cycle of this species. Females provided with brood pouches seem to be more numerous in the spring, as is the case with the subterranean amphipod Niphargus virei Chevreux. The average length of the incubation period seems much shorter than that of other troglobitic species such as Niphargus virei Chevreux or Caecosphaeroma burgundum Dollfus, so that the life cycle of our species is nearer to that of epigean Asellus. The number of young per brood appears to be related to the length of the female, as is suggested by our observations on 52 ovigerous females, but there must be other factors which influence this quantity. The comparison between our observations and those made on the North American cavernicole Asellus tridentatus Hungerford shows that the sexual biology of these two species is apparently quite different.

On a new species of Earthworm from a Mexican cave., 1968, Gates Gordon
Eodrilus mexicanus of the megadrile oligochaete family Acanthodrilidae is described along with some data as to development, regeneration and abnormality. Relationships with its American congeners, often inadequately characterized, are discussed and the present state of Eodrilus systematics is criticised. E. mexicanus seems likely to be of unusual interest as the second species of earthworm to have ovaries in segment xii.

Relations of jointing to orientation of solution cavities in limestones of central Pennsylvania, 1969, Deike Rg,
Twenty-six caves in central Pennsylvania were divided into passage segments inferred to have formed along the strike of fracture planes. For each cave passage, bearings weighted by footage were used to calculate an average passage orientation. Fractures measured at outcrops near the caves were classed by strike of subparallel sets which were cumulated by frequency for preferred orientations. Average passage orientation compared with orientation of fracture frequency was significant to the 95 percent level. Thus, caves develop more footage parallel to the strike of the more abundant fractures. Solution passages can therefore be used as one determinant of the local fracture system, and a selective solution process may be related to the mechanical origin of the fractures as well as their frequency

Olmec Cave Paintings: Discovery from Guerrero, Mexico, 1969, Grove David C. ,
A cave in Guerrero, Mexico, investigated in 1968, contained previously unreported Olmec paintings. These paintings, some of the oldest known in Mesoamerica, are stylistically similar to Olmec art from the site of LaVenta, on Mexico's Gulf Coast, but contain several important glyphic motifs never previously known to have existed at this time level. The iconography of the paintings confirms several important hypotheses concerning basic concepts of Olmec religion; the cave itself was probably a shrine to water and fertility. Several pre-Hispanic textile fragments found in the cave are probably from a later culture period

North American Troglobitic Salamanders: Some Aspects of Modification in Cave Habitats, with Special Reference to Gyrinophilus palleucus, 1971, Brandon, Ronald A. 1

A new species of the subterranean Amphipod genus Allocrangonyx (Gammaridae), with a redescription of the genus and the remarks on its zoogeography., 1971, Holsinger John R.
The systematics of the North American, subterranean amphipod genus Allocrangonyx are revised and two species are recognized; A. pellucidus (Mackin) and A. hubrichti, new species. Allocrangonyx is critically compared with the European genus Niphargus and several endemic North American genera of the Crangonyx group. Because of its unique morphological position, Allocrangonyx is removed from the Crangonyx group and placed in the newly designated AlIocrangonyx group. Some factors believed to have influenced speciation within the genus are discussed in some detail.
