Do places on Earth exist where annual records have been stored for tens of thousands of years and can be accessed today? Ice-cores and tree rings can preserve long records of yearly events but some of the best records come from layers of sediment underlying some lakes which, if formed under the right conditions, can be read like the annual rings of […]
Sudden catastrophic events are not unknown in Earth’s history. Large craters are evidence of past cosmic impacts. Widespread layers of volcanic ash are a testimony of massive volcanic eruptions. But when did these catastrophes occur and could they have impacted human history? Standard geological models place the largest catastrophic events many eons ago. So long […]
The human fossil record is probably one of these least understood yet frequently discussed topics in the Christian church. I have neither the expertise nor the desire to attempt to resolve the debate over whether particular fossils represent human ancestors or not. I understand that human origins is a sensitive topic, especially within the conservative evangelical church […]
William Buckland: Minister and Geologist Grappling with Fossil Feces, Deep Time and the Age of Reptiles
The Reverend William Buckland (1784-1856) was one of the last in a line of influential natural theologians following in the footsteps of John Ray (late 1600s) and William Paley (late 1700s). I recently gave a seminar in which I explored a number of significant turning points (figure below) in the history of discovery of deep time and the awareness […]
We live in a new golden age of fossil discoveries. It seems that every week a new and dramatic fossil find is revealed. This fossil renaissance can be attributed to the opening up of new fossil sources, particularly China and Mongolia but also South America and to improved technology for retrieving and analyzing fossil remains. […]
Remember the meteor that exploded over Russia earlier this year? A 50 foot diameter object exploded 14 miles above the surface of the earth and created a shock wave that injured 1500 people and damaged more than 7000 buildings. Despite the drama, the lasting effects on the earth were minimal and only small pieces of the meteorite made it to the surface of the earth.
Maybe you missed it last week with all the excitement of the pictures from Curiosity and its analysis of the rocks on Mars (See my last post: Curious Geology: Stunning Images Reveal a Complex Mars) but there was another pronouncement of further evidence that watery processes were once active on Mars. Where did this evidence […]
