This paper focuses on a learning strategy designed to overcome students' difficulty in understanding evolutionary change within the framework of geological time. Incorporated into the learning program "From Dinosaurs to Darwin: Evolution from the Perspective of Time," this strategy consists of four scaffolded investigations in which…

This document points out that creationists claim that humans and dinosaurs lived together in Texas just before Noah's flood by citing alleged human footprints found side-by-side with those of dinosaurs in the Cretaceous limestone of the Paluxy River near Glen Rose, Texas. An investigation was conducted to determine if this claim were true.…

Included are a teacher's guidebook and two filmstrips, "Geology of Wisconsin," and associated materials. The following are described: outline of objectives; suggested use of the filmstrips and guidebook; outline of the filmstrip content; four pages of illustrations suitable for duplication; a test for each filmstrip; and a list of…

Describes the unicellular microorganisms of three billion years ago. Explains how these primitive cells gave rise to biochemical systems and the present oxygen-rich atmosphere. Numerous diagrams, charts, and illustrations. (MA)

Describes the best-documented example of an ossuary in New England, which contained the bones of at least 56 people interred together about 1,000 years ago. Implies that the southern New England coast had a settled population centuries before the Pilgrims. (TW)

Recent developments in molecular biology and new interpretations of the fossil record are gradually altering and adding to Charles Darwin's theory, which has been the standard view of the process of evolution for 40 years. Several of these developments and interpretations are identified and discussed. (JN)

The article's thesis is that evolution's intellectual foundations have been steadily eroding, and that few new findings in embryology, taxonomy, fossil remains, and molecular biology are bringing us very near to a formal, logical disproof of Darwinian claims. The paper begins by discussing the evidence of a prehistoric world, then they discuss…

In Alberta, Canada, at the rim of the great western plains, an enthusiastic group has shown how teachers can have family fun while learning a lot of science firsthand -- at small financial cost. (Author)

Discusses causes of cyclicity in cratonic carbonate sequences and evidence for and potential significance of postulated primary calcite sediment components in past Paleozoic seas, outlining problems, focusing on models explaining existing data, and identifying background. Future sedimentary geologists will need to address these and related areas…

Discusses discoveries made during 1976 in various areas of invertebrate paleontology. (MLH)

Describes discoveries made in 1976 in areas of vertebrate paleontology, including research indicating that dinosaurs were warm-blooded. (MLH)

Researchers who study the fossil record are seeking to determine whether the impact made by a comet or meteor really did decimate up to half of the life on this planet at the end of the Cretaceous period. Questions whether the extinction of plant and animal life was abrupt, started before the impact, or was a gradual change. (KR)

Presents a geological tour of Arizona's Petrified Forest National Park, cited as containing the greatest record of life in the Triassic Period. Discusses ancient ecosystems, fossil records, geologic formations, petroglyphs, the Anasazi settlements, Painted Desert, and other park features. Includes an illustration of the fossilization process,…
