There is another possibility, ignored in secular science journals. A few theories have been wacky, such as the suggestion thatĭinosaurs died out from a plague of indigestion. Others have suggested that their numbers declined as dinosaursĪte each other. To be explained? Some scientists have suggested that the world’s climate suddenlyīecame too cold. If the impact theory is not correct, then how is the disappearance of dinosaurs The K-T Boundary: This visible boundary between two layers of strata (Cretaceous and Tertiary) is thought to be the result of a mass extinction. According to secular scientists, they record millions of years of history, but the Bible indicates that the layers were laid over the past 6,000 years. ![]() Geologic Table: The geologic table summarizes the earth’s rock layers. Volcanoes do produce iridium and spread it out.Īs a result of these and other problems, some evolutionary scientists do not In at least one case, the iridium would have taken half a million years to coverįar more likely is that the iridium enrichment came from volcanic activity, (In other words, areas around impacts are not iridium-enriched.) AlthoughĪsteroids do have iridium in them, they do not normally spread out the iridium That might follow the dropping of nuclear weapons.Ī third problem is that there is too much iridium to fit with the theory. Another problem is that the cloud would causeĪ long period of extreme cold, somewhat like the so-called “nuclear winter” For example, some extremely light-sensitive Variants of the theory, a comet rather than an asteroid caused the deadly impact.īut the theory has some problems. Such a huge impact would have sent a large dust cloud into the atmosphere,īlocking sunlight from the earth and causing some species to die out. FormationsĪt Chicxulub, Mexico, appeared to be the remnants of a very large impact crater. In 1990, the supposed “smoking gun” of the impact theory was found. The Alvarez team therefore suggested that this iridium came from a Originally molten and any iridium would have sunk to the core after millions That this could not have come from earth because they assumed the earth was The K-T boundary have an unexpectedly high concentration of iridium. The father and son team of Luis and Walter Alvarez discovered that rocks from This boundary, including many marine reptiles and plants. Million years ago on the evolutionary time-scale, and dinosaurs appear onlyĪt the bottom on the Cretaceous side. (Cretaceous rocks are indicated by a K to distinguish themįrom Cambrian rocks, which have a C abbreviation.) This boundary occurred 65 The most well-known extinction event is at the boundary between CretaceousĪnd Tertiary rocks. Whenever a number of organisms appear to be missing in a layer of rocks aboveĪnother layer where they are found, evolutionary geologists call this an extinction To understand this theory, you need to understand the term extinction event. It was formulated asĪ result of new studies of the so-called “K-T extinction event.” Whenever a number of organisms appear to be missing in a layer of rocks above another layer where they are found, evolutionary geologists call this an extinction event. The impact theory first gained popularity in the 1980s. ![]() This happened only to dinosaur eggs while birds’ eggs or other reptile eggsĭid just fine, but many people believed the theory. Too thin, so they were not hatching properly. Many years ago, I was taught that the shells of dinosaur eggs were becoming Over the years dozens of theories have been proposed. So it mayīe a surprise to realize how recent this theory is. The idea has been ingrained in our consciousness that dinosaurs died out becauseĪ large asteroid or comet hit the earth some 65 million years ago.
