Rock layers above the Cretaceous are consistent with findings expected in the waning half of the Flood year and the post-Flood time. Ultimately, even the larger dinosaurs were overwhelmed and buried. Footprints, often in patterns typical of uphill climbing, memorialize many animals’ final efforts to flee the rising waters. As the Flood waters rose, animals would have naturally sought higher ground. Many dinosaur footprints and body fossils are found in and below the Cretaceous layer. So how do creation scientists explain the disappearance of dinosaurs from the fossil record above the Cretaceous layer? Global Flood geology explains the fossil layers in the geologic column. Volcanoes, on the other hand, produce iridium and do tend spread their dust clouds worldwide.Īs the Flood waters rose, animals would have naturally sought higher ground. The dust from asteroid impact would not spread very far. There is, however, too much iridium to attribute to the asteroid. Evolutionary geologists believe the iridium came from space because they believe any iridium on earth should have sunk in our molten planet millions of years before the K-T layer was formed. Proponents of the asteroid hypothesis believe a layer of iridium at the K-T boundary came from the asteroid and spread all over the world. David Archibald adds, “Finding one fragment of dinosaur suddenly make this gap go away. “Sadly, it is only one bone,” says soil scientist Gregory Retallack, pointing out that gradual extinction would have allowed a few dinosaur bones near the boundary. Many evolutionary scientists disagree with Lyson’s interpretation of the find as strong support for the asteroid hypothesis. About two decades ago, dinosaur fossils were found at 60 cm and 37 cm below the boundary. Since that depth represented 100,000 years on the evolutionary timescale, it seemed dinosaurs were long dead before the fateful asteroid left its crater in the Yucatan Peninsula. When the asteroid extinction hypothesis was first proposed, the nearest dinosaur fossils were 3 meters (over 9 feet) below. The evolutionary timescale suggests the K-T boundary extinction occurred 65 million years ago. Not only do dinosaur fossils end at the K-T boundary, but also fossils of many plants and marine reptiles. The K-T boundary marks a so-called “mass extinction event.” Fossils of many species are virtually absent in layers above the boundary. Widespread volcanism is another suggested scenario that could have blocked sunlight needed to maintain the food supply for herbivores. Worldwide atmospheric dust blocking sunlight in the aftermath of asteroid collision is one such scenario. Numerous causes for dinosaur extinction have been proposed. ![]() But Lyson says, “Here we have a specimen that basically goes right up to the boundary, indicating that at least some dinosaurs were doing fine.” The gap between dinosaur fossils and the boundary suggests to other evolutionists that the dinosaurs were extinct long before the asteroid collision. The Cretaceous-Tertiary (K-T) boundary is thought by asteroid proponents to contain sediment deposited after an asteroid’s impact. A dinosaur fossil found in Montana’s Hell Creek Formation by Yale paleontologist Tyler Lyson just 13 cm below the boundary is “the closest bone to the boundary” yet found. Even those evolutionists who subscribe to the popular asteroid idea have difficulty explaining the lack of dinosaur fossils immediately below the K-T boundary. Science: “ Case Closed for Dino Killer?”Įvolutionary scientists for three decades have debated about the asteroid hypothesis of dinosaur extinction.
