Are fossil dating methods accuracy

These first “geochronology studies” yielded the first “absolute ages” from geologic material, which seemed to indicate that parts of the Earth’s crust were hundreds of millions of years old. During this same period of time Thomson (1905), Campbell and Wood (1906) demonstrated that potassium was radioactive and emitted beta-particles.

Both the physical geologists and paleontologists could point to evidence that much more time was needed to produce what they saw in the stratigraphic and fossil records.The study of geology grew out of field studies associated with mining and engineering during the sixteenth to nineteenth centuries.In these early studies the order of sedimentary rocks and structures were used to date geologic time periods and events in a relative way.At first, the use of “key” diagnostic fossils was used to compare different areas of the geologic column.Although there were attempts to make relative age estimates, no direct dating method was available until the twentieth century.
