    Obviously, faced criticism by the Catholic church and was called to Rome a few times to explain his Copernicus Theory.
  • Mediterranean Sea Used For Dating

    Edmund Halley uses the salinity and evaporation in the Mediterranean sea to determine the age of the earth.
  • Hutton Challenges the Theory of Catastrophism

    Hutton Challenges the Theory of Catastrophism
    Hutton found evidence of the earth developing its characteristics over a long period of time.

    Paper published by James Hutton.
  • New Dinosaur Bones Discovered

    This genus was named in 1824, by William Buckland, Megalosaurus bucklandii.
  • Dinosaur Models Begin Production

    Dinosaur Models Begin Production
    the first dinosaur models (life size and made of concrete) were made by Benjamin Waterhouse Hawkins of England.
  • Leon Teisserenc de Bort discovers that the atmosphere consists of layers.

    He used balloons with instruments attached to them and discovered (after many balloon experiments/trials) that the atmosphere is made up of different layers with different temperatures (stratosphere and troposphere was discovered).
  • Earth's Core Inspected

    Discovery of Earth’s core by seismologist Richard Oldham found that waves move slower through the center of the earth than they do the mantle; thus, the earth’s core is made of a liquid.
  • Pole Reversal!

    Pole Reversal!
    Pole (Magnetic Field) Reversal concept is introduced by Bernard Brunhes. His paleomagnetic study of clay baked by a Miocene lava flow 13 million years ago provides the evidence. It is nearly 50 years before his discovery is accepted by the scientific community
  • Seismic Moment

    Keiiti Aki discovers the seismic moment
  • MIT

    Physicist Luis Alvarez, geologist Walter Alvarez, and others propose that the impact of a large extraterrestrial object caused the extinction of the dinosaurs at the end of the Cretaceous Period (65 mya)
