Bird and mammal footprints are most common in the same stratigraphic intervals where their body fossils are common. However, reptile and amphibian tracks are more common in stratigraphic layers lower than their body fossils. Published in Origins v. 9, n. 2.

The cause of the 1908 Tunguska explosion in Russia remains somewhat mysterious. The most probable explanation is that a small comet exploded in the air and produced a blast wave that uprooted thousands of trees and killed many reindeer. Published in Origins v. 9, n. 2.

Analysis of the literary structure of the Flood narrative shows that it is the product of a single author, and not a compilation from various sources. Published in Origins v. 6, n. 1.

The effects of glaciers are well-dccumented in modern and Pleistocene sediments. Some Precambrian and Paleozoic sediments show some features similar to those of modern glaciation, but there is some controversy over whether the features are the result of glaciers, submarine landslides, lahars, turbidity currents, etc. Published in Origins v. 6, n. 1.

The account of the flood as given in Genesis is brief, and many different interpretations have been given to the events described therin. Three expressions used in that narrative will be analyzed below in an attempt to show their original meaning. Published in Origins v. 5, n. 2.

Experimental evidence shows that wood can petrify in a few years or less when immersed in mineral-rich water. Published in Origins v. 5, n. 2.

The presence of various kinds of megabreccias in the geologic column, showing in some cases the transport of extremely large clasts, indicates energy levels on a scale that staggers our imagination. Published in Origins v. 5, n. 1.

A new journal, Catastrophist Geology, has begun publication. Published in Origins v. 4, n. 2.

Clastic dikes form when unconsolidated sediments are forced upward into overlying sediments by the weight of the accumulating sediments. Some clastic dikes intrude into layers supposedly many millions of years younger, indicating that the underlying sediments remained unconsolidated for unexpectedly long periods of alleged time. Such features challenge the conventional geologic time scale. Published in Origins v. 4, n. 1.

Major tektite falls in Australia in strata as young as 5700 years old according to radiocarbon dating have called in question both the fission-track and the K-Ar methods of dating which assign these identical tektites an age of about 700,000 years. Published in Origins v. 3, n. 2.

A review of two articles: On the Survival of Paleoforms, and The Tempo of Geomorphic Change. The scientific data of both papers indicate that much greater caution is warranted in approaching questions regarding the length of time involved in the past history of the earth. Published in Origins v. 3, n. 2.

There are two conflicting schools of interpretation regarding the extent of the Genesis flood. Traditionally the Biblical flood narrative has been understood to refer to a universal catastrophe, but on the basis of considerations from the natural sciences, commentators and interpreters began to seek for a limited flood theory or relative view of the Genesis flood. Published in Origins v. 2, n. 2.

A review of the book, The Nature of the Stratigraphical Record. The geologic record can be described as long periods of relative calm punctuated by brief catastrophic events. Numerous geologic features can be traced over large portions of the earth's surface. Published in Origins v. 2, n. 2.

This new concept indicates that some events in the past history of the earth may have proceeded much more rapidly than was previously believed. Published in Origins v. 2, n. 2.

A tiny marine worm, Spirorbis, constructs a calcareous tube, and is often found attached to shells and debris in the ocean. Fossil Spirorbis are sometimes common in coal beds. Some have suggested Spirorbis lived in fresh-water habitats in the past, but this is highly unlikely. It is more likely that coal formed in marine waters during the Flood.

The words "burst forth" correspond to the words "were opened" and the expression "the fountains of the great deep" corresponds to the "windows of the heavens." This chiastic parallelism indicates that the waters below the ground came forth as the waters above the ground broke loose. Published in Origins v. 1, n. 2.
