Thirsk is 45 kilometres from the sea, and the garage owner thought that this collection of marine life arrived with the torrential thunderstorms during the night.

In the years that have followed, the inability to explain the idiot savant has not lessened, and the challenge to our capabilities remains undiminished.

Why is there a 6:1 male-to-female ratio in this disorder?

Dinosaurs are now becoming more lively and talented; they may even have been warm-blooded! A recent paleontological expedition to the Gobi Desert by some Canadians will change the dinosaur stereotype even more. The Gobi dinosaur-bone sites are incredibly rich -- comparable with those in Alberta. What is most impressive, however, is the environment the Gobi dinosaurs lived in. "The dinosaurs of China and Mongolia did not live in the same type of lush, well-watered environment that existed in North America during the Mesozoic era, when dinosaurs dominated the globe. The dinosaurs of Alberta flourished on a great swampy coastal plain on the edge of a vast inland sea. In ancient China, conditions were much harsher. A modern-day equivalent would be the Great Salt Lake Basin of Utah. Water did exist in vast shallow lakes, but it was often alkaline and high in soda. The vegetation was scrubland with coniferous forests on the higher ground." (Anderson, Ian; "Chinese Unearth a Dinosaurs' Graveyard," New Scientist, p. 26, November 12, 1987.) Comment.

Measurements of one ice stream flowing down from the mountains to the sea in dicate a sudden unexplained, 20% reduction in speed over the past decade. Perhaps even more significant is that, even with this reduction in flow velocity, this particular ice stream carries ice into the sea 40% faster than ice accumulates up in the mountains. The sudden, rather large velocity change is alarming because it may signify widespread instability in the continent's icy mantle.

At the helm, Philip Sefton, 22, fought the angry waves that now confronted them. "Suddenly a heavy gust of wind pushed the Marques down on its starboard side. At the same instant 'a freakish wave of incredible force and size,' as Sefton later described it, slammed the ship broadside, pushing its masts farther beneath the surging water. A second wave pounded the ship as it went down. The Marques filled with water and sank in less than one minute. Most of the crew were trapped as they slept below deck.

The bones of the leatherback are more like those of the marine mammals (dolphins and whales) than the reptiles. "No one seems to understand the evolutionary implications of this." Leatherbacks dive as deep as 3000 feet which is strange because they seem to subside almost exclusively on jellyfish, most of which are surface feeders.

Further, crater density counts for Chryse and the Martian highlands imply that Mars possessed a fairly dense atmosphere until about 1.5 billion years ago. In his Abstract Helfer speculates as follows: "With both early Earth and early Mars having similar atmospheric compositions and not too dissimilar atmospheric structures, it is reasonable to suppose that the warm Martian oceans, like the ancient oceans of Earth, would develop anerobic and aerobic photosynthesizing prokaryotes and structures like stromatolites.

These muffled detonations heard near the coasts of almost all the continents are believed by some to be caused by eruptions of methane from the seafloor. The same eruptions probably also account for the myriads of "pockmarks" found in the sediments of shallow seas. Whether this outgassing of methane comes from shallow accumulations of organic matter or from deep within the crust is still debated. Here, geophysics merges with biology. Recently, a group of researchers discovered a large (540 square meters) patch of chemosynthetic mussels in a brine-filled pockmark, at a depth of 650 meters, off the Louisiana coast. The mussels grew in a ring around the concentrated brine. The mussels harbor symbionts which consume the methane still seeping up through the brine from a salt diapir (a massive fingerlike intrusion 500 meters below the brine pool. The origin of some diapirs is not well-understood.) The mussels get the oxygen they require from the ordinary seawater covering the dense brine.

By subtraction, the oil might be as young as 1240 years! The picture geologists draw of the Guaymas Basin is that of a spreading center covered by perhaps a half kilometer of sediments. Spewing up from the spreading center is hot water at 300-350 C, which "cracks" the organic material in the sediments, converting it into petroleum only 10-30 meters below the sea floor.

(Fassbinder, Jorg W.E ., et al; "Occurrence of Magnetic Bacteria in Soil." Nature, 343:161, 1990.) Comment. It is easy to reach great heights of speculation given the facts that: (1 ) magnetic bacteria exist; (2 ) bacteria in general are exceedingly abundant; and (3 ) bacteria are found deep inside the earth's crust and, seemingly, just about anywhere one cares to look. Now, let's see how ridiculous one can get: Magnetic bacteria and/or their fossils contribute heavily to the magnetic properties of sedimentary rocks and unlithified sediments, such as deep-sea sediments. In fact, magnetostratigraphy and paleomagnetism in general may be based upon bioartifacts and be suspect. Magnetic bacteria and/or their fossils are present in such immense numbers deep in the crust that they contribute significantly to the earth's magnetic field. They "might" even be responsible for most of it, including its his torical behavior. Magnetic bacteria, as agents of Gaia, actually constructed the earth's magnetic field for the specific purpose of erecting a shield against space radiation, and thereby allowing the development of more complex life forms on the planet's surface.

If the latter, the flow was probably from Asia to America because the paper-making tools first appeared in Southeast Asia 4-5000 years ago and in Mesoamerica only 2500 years ago. Even so, trans-Pacific voyages 2500 years ago are definitely not part of acceptable archeology. Anthropologist P. Tolstoy, swimming against the mainstream, has surveyed the manufacturing technology of both bark paper and ordinary paper on a worldwide basis. He identified some 300 variable features in the process, 140 uses of the final products, and 100 specific details of bark beaters. Tolstoy concluded: "All this points to the direct transfer of technology from Southeast Asia to Mesoamerica, apparently by a sea voyage that took place about 2500 years ago." Tolstoy rejects the tapa (bark cloth) of Polynesia as a credible link between Southeast Asian and Mesoamerican barkpaper making. The technology transfer was not island-to-island but direct!

Take the Pennsylvanian period for example. It is part of the Carboniferous period, when many of the great coal deposits were laid down. The classical duration of the Pennsylvanian -- used in many texts -- is 34 million years. A meticulous new study of central European stratigraphy now pegs the Pennsylvanian as spanning only 19 million years. Now that's a 44% change! This new figure for the duration of the Pennsylvanian has already cast doubt on the origin of the famous Pennsylvanian cyclothems (repetitive strata) in North America. It had been thought that these seemingly cyclic deposits were correlated with sea level changes forced by variations in the earth's orbit (the Milankovitch periods). With this substantial compression of Pennsylvan-ian time, this correlation falls apart. The cyclothems, which are of impressive area and thickness, now seem to have been created by some other, still unrecognized phenomenon.

Nansen first endeavored to go as far north as he could in his specially constructed vessel, the Fram . It was on the Fram that he struggled with "dead water." J.M . Walker, drawing from Nansen's marvelous written account Farthest North , describes the phenomenon: "Towards the end of August 1893, when Fram was off the Taymyr Peninsula, near the Nordenskiold Archipelago, 'dead water' was encountered. In the words of Nansen, this is 'a peculiar phenomenon', which 'occurs where a surface layer of fresh water rests upon the salt water of the sea, and this fresh water is carried along with the ship, gliding on the heavier sea beneath as if on a fixed foundation'. It 'manifests itself', he observed, 'in the form of larger or smaller ripples or waves stretching across the wake, the one behind the other, arising sometimes as far foward as almost midships'. When caught in dead water, Nansen reported, Fram appeared to be held back, as if by some mysterious force, and she did not always answer the helm. In calm weather, with a light cargo, Fram was capable of 6 to 7 knots. When in dead water she was unable to make 1.5 knots.

"At the same time as the above form of bioluminescence, there seemed to be a second type but it was difficult to pinpoint the source.

Here are found free-living bacteria, tube worms, molluscs, and several other species that prosper without the benefit of photosynthesis. These chemosynthetic, thermal-vent communities are separated by thousands of kilometers of sea-floor "desert." Yet, the species involved are similar worldwide and must, at some time, have crossed these wide, forbidding expanses.

The whale's skeleton was covered with bacterial mats like those at the hydrothermal vents. Also sustained by the carcass were mussels, snails, and worms; all in all, a community much like those at the vents. Furthermore, many of the species partaking of the whale's energy and chemical resources are not normally found in that part of the Pacific. Subsequently, more "whale falls" with attached biological communities were found elsewhere.

Strange tube worms up to six feet long have been discovered off the Spanish coast, dining on the hydrogen sulphide from rotting beans [beams?] in the hold of a ship that sank 13 years ago. Lacking mouth, gut and anus, they rely on bacteria to process the nutrients in minerals and dissolved in sea water. They had been found previously in the Pacific and the Gulf of Mexico. It was thought they liked to live in huge colonies around cracks in the ocean floor where hot, mineral-rich lava pours out and areas where oil and gas leak from the seabed."

"The 300-degree ground temperature has caused plants to wither in the mountainous region of Diyatalawa, a tourist resort in central Sri Lanka, said D.A . Kathriarachchi, the deputy director of the Geological Survey Department. "He said scientists were puzzled because there is no volcanic activity in Sri Lanka, which lies outside any volcanic zone. "The area, about 75 miles southeast of the capital, Columbo, is 9800 feet above sea level. The villagers have been told to report any other signs of smoke in the area, but no one has been evacuated."

Category ESC4, in Anomalies in Geology, describes the "Smoking Hills" of the Canadian Arctic, as well as several other places where the oxidation of iron pyrite and other exothermic chemical reactions create very hot areas in non-volcanic regions.

... ice would have the destructive power of 20 million megatons (1 .6 million Hiroshima bombs). (Anonymous; "Astronomer Predicts Comet Collision," Baltimore Sun, October 26, 1992.) Some recent meteorite impacts. Turning from the dire consequences discussed above, just what sort of astronomical debris actually does hit the earth on a day-to-day basis? Fist-sized meteorites strike our planet about every two hours. These are the ones we read about in the newspapers; and they have left a surprisingly large legacy of damage to human structures. C. Spratt and S. Stephens, in a survey published in Mercury in 1992, listed 61 verified meteorite strikes since 1790 in which buildings and other human works were damaged. (Of course most fell harmlessly in the sea and unpopulated areas.) Spratt and Stephens also provide a table of 26 nearmisses of humans plus one confirmed human impact. At least one horse and a dog have been killed by meteorites. These lists make engrossing reading, but we cannot take the space to reproduce them here.

Science Frontiers ONLINE No. 104: Mar-Apr 1996 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The whale-on-its-tail fossil Near Lompoc, California, is a large deposit of diatomaceous earth, so-called because it is composed almost entirely of countless billions of exquisitely sculptured diatom skeletons. Uniformitarian geologists have steadfastly maintained that such diatomaceous-earth deposits require millions of years to form as the tiny skeletons sink slowly to the sea floor. At Lompoc, however, embedded in the thick layer of diatomaceous earth is the fossil of a large whale apparently standing on its tail. How could this whale fossil have maintained its position and integrity over hundreds of thousands of years as it was buried millimeter by millimeter? Wouldn't the bones have been quickly scattered? Creationists have pointed to this whale as proof that the Lompoc diatomaceous-earth deposit was formed catastrophically, interring the whale almost instantaneously, and burying doctrinaire uniformitarianism at the same time. (Creationists want to "shorten" geological time to fit Biblical schedules.) But was the whale really entombed on its tail? Creationist geologists studied the Lompoc deposit and put a different slant on the story but not on its ending. "Contrary to some reports that have circulated, the 80-90 ft (24-27 m) long fossilised baleen whale found in April 1976 in an inclined position in a diatomite unit in the Miguelito Mine at Lompoc, California, was not buried while 'standing on its tail'. An onsite investigation has revealed that the ...

... translucent, strikingly green bergs originate. "A comparison of samples from a translucent green iceberg with a core from the Ronne Ice Shelf revealed an excellent agreement in isotopic composition, crystal structure, and incorporated sediment particles. Marine shelf ice which constitutes the basal portion of some ice shelves is considered to be the source of green icebergs. It [the green ice] most likely results from 'ice pump' processes which produce large amounts of ice platelets in the water column beneath ice shelves. These subsequently accumulate and become compacted into bubble-free, desalinated ice." The inclusions in the green ice are probably trapped by the accumulating platelets. Since the green ice is confined to the bottoms of the bergs, it becomes apparent only after the bergs capsize. The green icebergs in the Weddle Sea originate mainly from the Amery Ice Shelf. (Kipfstuhl, J. et al; "The Origin of Green Icebergs in Antarctica," Journal of Geophysical Research, 97:20,319, 1992.) Similar phenomenon. The ice calving from Alaskan glaciers is often a beautiful blue color -- the consequence of the ice's high density rather than inclusions. Alaskans export this ice to Japan where it is popular in drinks at tony parties!. From Science Frontiers #87, MAY-JUN 1993 . 1993-2000 William R. Corliss ...

... indicate that the final glacial epoch occurred late in Martian history. Thus, Mars may have had a relatively warm, moist climate and dense atmosphere much later than previously believed." (Kargel, Jeffrey S., and Strom, Robert G.; "Ancient Glaciation on Mars," Geology, 20:3 , 1992.) If Mars was warm and wet not too long ago, as implied above, perhaps life did gain a foothold there through either independent invention or, perhaps, through seeding by template-carrying comets or meteorites. P.J . Boston et al have investigated one possible Martian ecosystem: "We have reexamined the question of extant microbial life on Mars in light of the most recent information about the planet and recently discovered nonphotosynthetic ecosystems on Earth -- deep sea hydrothermal vent communities and deep subsurface aquifer communities. On Mars, protected subsurface niches associated with hydrothermal activity could have continued to support life even after surface conditions became inhospitable. Geochemical evidence from the SNC meteorites and geomorphological evidence for recent volcanism suggest that such habitats could persist to the present time...We suggest a possible deep subsurface microbial ecology similar to those discovered to depths of several kilometers below the surface of the Earth." (Boston, Penelope J., et al; "On the Possibility of Chemosynthetic Ecosystems in Subsurface Habitats on Mars," Icarus, 95:300, 1992.) Comment. Although Boston et al speak in terms of microscopic Martian life, there is no reason why chemosynthetic life forms could not be large -- perhaps even large enough to leave ...
