thank to Mount St. Helen. The fossil records‚ Distant starlight theory and Big Bang theory all show no concrete evidence for an old earth. 3.The lack of fossil records ‚ to link both man and apes fossil records clearly speaks for them not having had one. Lucy the ape‚ depicted as having human hands and feet and which currently stands in the museum of natural history‚ is on display as one of our oldest ancestors.

The eras and periods of the geological time column were established using relative time (mostly based upon the fossil content). Absolute Time - The discovery of radiometric dating allowed geologists to assign a numerical age to the formation of certain rocks.

Soltisand Douglas E. Soltis‚the fossil record that they found out does not clarify basal groups within the angiosperms. However‚ it clearly identifies a number of form and structure of diverse lineages early in angiosperm evolution. The earliest known large fossil confidently identified as an angiosperm‚ Archaefructusliaoningensis‚ is dated to about 125 millionyears or also known as Cretaceous period‚ whereas pollen considered to be of angiosperm origin takes the fossil record back to about 130 million

it was very common for them to uncover dinosaur bones. In fact‚ a T-Rex skeleton was found in a suburb of Denver. However‚ they do not consider this their greatest find in this area. They managed to come across a serrated tooth. This was the prize fossil at the site. In 1994‚ they came across a dinosaur rib while building the Colorado Rockies stadium.

Although these were said to be the “oldest” there have been more modern research done that shows DNA comparisons of ancient fossils and more recent bones. This evidence is known as the clue to the ancestor of all cats including the domestic cat‚ margay‚ and marbled cat. In China‚ Archaeologists have found the first clear evidence of domestic and/or

feathers that are complex‚ a fused clavicle‚ short bony tails‚ bones that are filled with air sacs‚ efficient breathing‚ and a fast growth rate. When comparing fossils to birds‚ they had many of the same features. Some dinosaurs had feathers‚ Dr. Curry Roger’s provided us with pictures of these feathers. Additionally‚ the bones of these fossils also showed evidence of air sacs and had reached sexual maturity quickly‚ showing that they too were fast growers. Additionally‚ new evidence shows that dinosaurs
