Many people alive today have seen identical tracks in the sand along a river bank, or at the beach.
In the second, it was already believed, due to the presence of sandpiper tracks, that the formation had to fit within the neo-Darwinian timeline for bird evolution—and the geologists again received the date they were expecting.
An episode of geologic thrust-faulting in the past was invoked as a ‘just-so’ story in an attempt to explain the 175-million- year difference in dates.
Such faulting can result in older strata being pushed on top of younger strata, and older rocks, it was said, were mistaken for younger rocks when the first dating was done.
by Jonathan O'Brien Using well-known radioisotope technology, scientists dated the Santo Domingo rock formation in Argentina at 212 million years old.
This happened to agree well with a nearby geologic formation that was also radiometrically dated.
The radiometric date of the Santo Domingo formation also agreed with the dating based on fossil wood found entombed in the rock.This wood came from an extinct species of tree conventionally believed to have existed around 200 million years ago.Well-preserved and abundant tracks were also found in the rock, similar in appearance to bird tracks.The scientists, who assert that the earth is billions of years old, concluded that the footprints must have been made by an unknown species of a small bird-like dinosaur, because according to Darwinian theory birds weren’t supposed to be around 212 million years ago.The results were accepted and published by the science journal in 2002.But recently, a different group of long-age-believing scientists took a fresh look at the bird-like dinosaur footprints and concluded that they were indeed made by birds after all—actually, by the familiar sandpiper of today, a small bird common to wetlands, grasslands and coastal habitats around the world.
