| 16 -- FOSSILOLOGY | ||
| The fossil record is crucially important to evolutionists because, as Darwin immediately realized, it is the one and only possible source of the information required to validate his theory according to the requirements of the scientific method. [Ed: It’s a good idea to know a bit about fossilology, G-Man, in case some evolutionists get you in a corner and try to duff you up.] The
Origin of Some Geological Terms Many of the strata or layers of rock depicted, identified by particular fossils they contained, were originally named after the locations in which early geologists identified them – Cambrian, for example, coming from the Roman name of Wales, and Devonian strata (the Age of Fishes and Ferns—including armoured fish) having first been recognized in Devon. The Cretaceous strata, however, as illustrated by the white cliffs of Dover and composed mostly of micro shell fossils, were named, because of their composition, from the Latin for “chalk”. The Cambrian and Silurian (named after an ancient Welsh tribe) strata were identified by Roderick Murchison about 1835 and traced through various parts of England and Wales on the basis of the fossils they contained, links sometimes also being made on the basis of banding patterns in the sediments. This technique, called “bio-stratigraphy” was apparently taught to Murchison by engineer and canal builder William “Strata” Smith, who had used ammonite fossils to correlate Mesozoic outcrops and excavations in various locations. Although not interested in publishing his ideas, Smith was happy to discuss them with other members of the “Geological Society of London”. Notice that the geological column is notional and does not exist in its entirety anywhere on earth. Be aware also that, according to standard geology theory, the formation of each new and younger set of strata necessarily required the destruction and recycling of earlier strata and their fossil content – implying immense potential complexity and confusion. That said,
however, there need have been no destruction and recycling of older
strata if all the Palaeozoic and Mesozoic formations were laid down
in one massive, world-wide catastrophe which sorted the marine creatures
into the lower strata and the larger, land-dwelling ones in the higher.
Additional material would of course have been required to form the more
recent Cenozoic formations. As already noted, fossil content is the important factor in identifying and correlating strata in different locations – which is why strata with the same fossil content may be composed of totally different rock material in different locations. As an illustration of the use of “index fossils”, the start of the Devonian period is now defined by the first appearance of fossils of the grapolite “Monograptus uniform”. No marker is suggested for the “end” of the period. Although sedimentary rocks are dated by their index fossil content, based in turn on questionable assumptions as to their age, rocks of volcanic origin can be dated by radiometric methods, as we shall discuss later. Unconformities Simple as the picture appears, there are problems and complications – for example, in situations where strata identified by their fossil content as being “younger”, e.g. type “A”, are found lying underneath “older” strata, e.g. type “C”. Such “unconformities”, are neatly explained away by the strata all having been flipped over by a massive earth movement – or by an “overthrust”, where a block of strata has been lifted up, thrust sideways, and plonked down somewhere else, thus depositing its older lower strata on the top of younger surface ones. In this manner, observations that contradict the evolutionary story are explained away or quietly ignored. Creationist

Key Fact How
Fossils Form As a result, the fossil record is, even now, relatively meagre – and since the organisms most likely to be fossilized are sea creatures with solid shells, that record presents a seriously distorted picture of the flora and fauna of any particular time, compounded numerically by the fact that some marine organisms, such as the trilobites, apparently grew and discarded several shells during their lifetime. The burial and fossilisation of organisms on the sea bed is favoured by the accumulation of sediments which fall continuously like fine snow, For land organism to be fossilized, some kind of catastrophe or accident is probably required in order to bury and preserve their remains. Little wonder that 99% of the fossil record consists of marine organisms, with coal beds being the prime source of plant fossils. Notice that although the fossil record is comparatively meagre, as Darwin claimed, it still does not support his claim that the overwhelmingly vast majority of fossils should be those of “missing links”, imperfect and failed forms. Whole
Body Fossils Bizarrely, some creatures were killed so quickly that their final postures were also preserved – for example, a fish swallowing a smaller one, a marine creature giving birth, and even, one source claims, a mating mammoth with its long male member still in a state of erection. A small Siberian mammoth was found with the grass and buttercups, remnants of its last meal, still in its mouth. Most fossils are actually mineralised copies of the organism structure, sometimes both external and internal – created by a process of petrifaction in which organic tissues are replaced by elements such as calcium and magnesium. Usually, the finer the sediment that bury an organism, the finer the detail of the resulting fossil, which is why the flying reptile Archaeopteryx is known to have had feathered wings. Anomalous
Fossils Polystrate
Fossils Polystrate fossils are common in coal beds and were recognized as a “mystery” by geologists over a hundred years ago. The orthodox explanation is that a tree took root in a marsh, then died and stood there without rotting for hundreds of years and actually assisted the formation of further coal seams by helping entangle floating mats of vegetation around it when the area was flooded again. As already mentioned, uniformitarianism does allow for relatively rapid acting local floods and changes to occur and for the formation of several seams of coal to take place in just a few hundred years, rather than millions. A study websites devoted to such palaeontological problems soon confirms the sheer complexity and the speculative nature of the subject. The
Coelacanth Since that time, however, hundreds more specimens have been netted, some of them about four feet long, somewhat bigger than the ancient version.. It is reported that in 1986, German biologist Hans Fricke studied these strange creatures at great depth using a miniature submarine – and discovered that they are equipped to swim in all directions, including backwards and upside down. Coupling this discovery with that by Japanese fishermen of what appeared to be a 10 metre long Pleisosaur kind of creature, a Loch Ness Monster look-alike, one wonders how many more apparetnly “extinct” organism remain to make their re-appearance. Pre-Flood
Creatures The mammoth, with its woolly coat, and no doubt other internal adaptations, would seem to provide an excellent illustrations of Hough’s suspicion that organisms, or at least populations of organisms, can actually sense their environment and respond to its needs in a creative manner, rather than waiting in hope over millions of years for the accumulation of accidental DNA copying errors to somehow save it. Mass
Extinctions As we shall
see a little later, however, most of the fossil record is totally irrelevant
anyway to the discussion at hand – since, with the exception of
some most recent additions, it simply represents the flora and fauna
of a pre-Adamic age - ancient organisms did not disappear because they
evolved into modern organisms, but because, as geologists now assure
us, they were destroyed, like the dinosaurs, by a series of mysterious
but massive cataclysms that befell the earth – as clearly evidenced
by the state of the moon’s surface, and that of each other planet
that NASA gets a closer look at. |
