Multiple cosmic impacts 790,000 years ago |

Approximately 790,000 years ago, there were multiple cosmic impacts on earth with global consequences. Geoscientists from Heidelberg University reached this conclusion after dating so-called tektites from various parts of the world. The research group under the direction of Prof. Dr. Mario Trieloff studied several of such rock glasses, which originated during impacts of asteroids or comets.

Siccar Point is an iconic geological site on the east coast of Scotland, famous for Hutton’s Unconformity found in 1788. James Hutton was a Scottish geologist whose work contributed to the understanding of landscape-forming processes and the concept of geological time. This video by the British Geological Survey offers excellent footage of the historical unconformity, where gently sloping red sandstone overlies steeply dipping grey sandstone. The age difference between the two is approximately 65 million years. “We can see what Hutton understood at the time: that there is a huge change in Earth’s history recorded in these two contrasting sequences of rocks, and that a vast span of time would have been required for these processes to take place.”

All this changed in…

Ammonite Fossils |

These spiral shells are fossils of an extinct species of marine animals called ammonites. Ammonite fossils are fairly common and serve as excellent index fossils. Index fossils are fossils used to reliably identify geologic time periods. The presence of ammonite fossils usually indicates a Jurassic (200 million to 145 million years ago) or Triassic (250 million to 200 million years ago) time period.
