Book excerpt: Excerpt from Foraminifera From Venezuela and Trinidad The collections upon which this article is based were made in Venezuela for an American company and in Trini dad by Prof. Harris. Only descriptions of species with general localities and general ages can be given at present, but later when the interests of the company permit, we hope to publish definite localities and stratigraphic ranges for the species. Fine distinctions between species and sub species have been made for stratigraphic purposes; further work may make still closer distinctions advisable. Among the many people to whom acknowledgments are due for help in this article are especially: Prof. G. D. Harris for material from Trinidad and for the use of his laboratory at Cornell University. Prof. F. L. Whitney of the University of Texas for an abundance of specimens of various species of Orbitolina from Texas and France for comparison.

This book was released on 2018-11-17 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Introduction to the Study of the Foraminifera That our work will prove altogether satisfactory, either to the scientific or to the general reader, is more than we can venture to anticipate. Those who look for precise definitions will not find them here, for the simple reason that the conclusion has been forced upon us that s/mrply defined dz'visz'ons - whether between species, genera, families, or orders - do no! Ewz'st amony Fommz'm'fem. And we are satisfied that any one whose study of the group shall have been coextensive with our own must be ready to this extent to endorse our results. It has been our aim, therefore, to set forth (so to speak) the fundamental idea of each of the generic types we have adopted, rather than to attempt a precise limitation of its boundaries. That some of our generic distinctions may be invalidated by more extended research, is just as likely as that new generic types may present themselves among the collections from ocean beds yet unexplored, or from geological formations as yet unscrutinised. The whole study of this group must still be regarded as in its infancy; and the utmost that we can hope for thislntroduction is, that it may help to give'a mm; direction to that'study. We have the fullest confidence in the correctness of our general principles; and shall not shrink from the consequences of their application to our own work, however large a part of it may thereby be superseded by something better. I have endeavoured throughout my own scientific career to keep in view the noble character given by Schiller of the true philosopher, as distinguished from the trader in science, that he has always loved truth better than his system and will gladly exchange her old and defective form for a new and fairer one. And the readiness with which my coadjutors have accepted my amendments in the instances already alluded to, affords the fullest assurance of their thorough participation with me in the desire, not only that whatever is defective in our joint work may be supplied, but that what is unsound may be demolished, since what shall remain really good and true will then afford a firmer basis for the future labours of others.

Download or read book The Foraminifera written by Frederick Chapman and published by . This book was released on 2015-07-27 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Foraminifera: An Introduction to the Study of the Protozoa The classical volume of Dr. W. B. Carpenter, written in conjunction with Professors Kitchen Parker and Rupert Jones, is still an exceedingly valuable book for workers in this special branch of study, for it contains the pioneer work of those authors on the morphology and microscopic shell structure of Foraminifera. The monographs of Drs. W. C. Williamson and H. B. Brady are also indispensable as works of reference. But these and others more recently published are voluminous and not always easily accessible to the student; whilst the increasingly large number of smaller works on the subject, written by Continental, English, and other authors, which have from time to time appeared in the various publications of Scientific Societies and in periodicals and journals, are quite outside the scope of the general student's reading.

Book excerpt: Excerpt from The Foraminifera of the Atlantic Ocean Except for the work of Dr. James M.

The region of the North Sea and the waters about the British Isles have been the source of a great mass of published records and a comparison with that area is very interesting.

It is based upon the known geologic his tory of the genera, upon the phylogenetic characters through a study of much fossil material and finally by a study of the ontogeny in very many microspheric specimens which show the relationships much more definitely than do the megalospheric specimens of the same species.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Philosophical Transactions, Vol. 3: Researches on the Foraminifera 145. Another marked feature of difference among the specimens of this Collection, is the depression or elevation of the central region relatively to the peripheral. In what I have assumed as the typical form, the central region presents the same general level with the rest, though the umbilicus itself is often marked by a prominent tubercle. In such forms as are represented in Plate 111. Figs. 1 and 2, the umbilical region is rather depressed than elevated; and this depression is often observed in older specimens whose early growth has taken place on.this type. But there is a group of specimens, of which three successive ages are represented in Plate III. Figs. 3, 4, 5, 8, that have the whole central region so exceedingly prominent as to form a cone, -whose apex is marked either by one large tubercle, or by a cluster of smaller ones; and this conformation gives so peculiar a physiognomy to the shells which present it, that few systematists would hesi tate in placing them apart as specifically different from the rest. On a careful compari son of a large number of individuals, however, it becomes apparent that this difference, like the preceding, is gradational; every degree of prominence being traceable from the individuals which have the umbilicus marked only by a tubercle, as in fig. 7, through those In which the region generally is slightly elevated, as in fig. 8, to those 111 which it presents the most marked projection, as in figs. 3 5. We shall presently find (fl' 153) that this difference depends mainly on the degree in which the investing layer, prolonged from the later convolutions over the surface of the earlier, is separated from that surface by the extension of the alar prolongations of the chambers of the investing whorls; as to which point there is a most remarkable diversity, not only among different individuals, but between the several convolutions of the same individual.

Book excerpt: Excerpt from An Index to the Genera and Species of the Foraminifera Systematic work on Foraminifera during the past forty years has received a tremendous impulse from their economic value, especially that concerned with the search for petroleum and more recently with ecologic and paleoecologic studies. At present there is a larger number of paleontologists actively engaged in foraminiferal studies than is specializing in any other group of the invertebrates. Because of the daily increasing volume of published material, it is difficult to keep abreast of nomenclatural changes in current work.

Download or read book Urumaco and Venezuelan Paleontology written by Marcelo R. Sánchez-Villagra and published by Indiana University Press. This book was released on 2010-07-16 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urumaco and Venezuelan Paleontology offers a synthesis of the paleontological record of Venezuela, including new discoveries on stratigraphy, paleobotany, fossil invertebrates, and vertebrates. Besides providing a critical summary of the record of decapods, fishes, crocodiles, turtles, rodents, armadillos, and ungulates, several chapters introduce new information on the distribution and paleobiology of groups not previously studied in this part of the world. Given its position in the northern neotropics, close to the Panamanian land bridge, Venezuela is a key location for understanding faunal exchanges between the Americas in the recent geological past. The book reviews the recent paleobotanical and vertebrate fossil record of the region, provides an understanding of Pleistocene climatic change and biogeography for the last few thousand years, and integrates new information with summaries of Spanish language works on Venezuelan geology and paleontology.
Download or read book Exploration of the Seas written by National Research Council and published by National Academies Press. This book was released on 2003-11-04 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the summer of 1803, Thomas Jefferson sent Meriwether Lewis and William Clark on a journey to establish an American presence in a land of unqualified natural resources and riches. Is it fitting that, on the 200th anniversary of that expedition, the United States, together with international partners, should embark on another journey of exploration in a vastly more extensive region of remarkable potential for discovery. Although the oceans cover more than 70 percent of our planet's surface, much of the ocean has been investigated in only a cursory sense, and many areas have not been investigated at all. Exploration of the Seas assesses the feasibility and potential value of implementing a major, coordinated, international program of ocean exploration and discovery. The study committee surveys national and international ocean programs and strategies for cooperation between governments, institutions, and ocean scientists and explorers, identifying strengths, weaknesses, and gaps in these activities. Based primarily on existing documents, the committee summarizes priority areas for ocean research and exploration and examines existing plans for advancing ocean exploration and knowledge.
