with Paleodictyon are commonly found in ysch sediments distributed all over the world (Kern 1978; Kushlin 1982). Modern patterns of Paleodictyon spp. are still being found on deep-sea sediments (Rona and Merrill 1978; Ekdale 1980). The most recognizable form, Paleodictyon nodosum, is characterized by rows of holes that intersect at an angle of

Hence, channel axis and proximal fan deposits tend to be dominated by the Ophiomorpha rudis subichnofacies. The Paleodictyon sub-ichnofacies is more typical of the lower energy lobe/fan fringe subenvironments. Proximal but off-axis areas are characterized by a mixture of the Ophiomorpha rudis and Paleodictyon sub-ichnofacies.

Whatever organism was responsible, it was thought to have become extinct about 50 million years ago, until the recent discovery of mysterious arrays of holes (bottom) that might overlie a similar tunnel network.

The men decided to touch down on top of a mesa to explore the landscape. They had not been on the ground long when a red disk, 8 feet in diameter, descended slowly from the sky. As the strange object touched down, Wood and his colleagues realized that it was some sort of animal. It appeared to be "breathing" by raising its top half up and ...
