From Today in Science History:On this day in 1953, the journal Nature published a paper from Francis Crick and James Watson, titled Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid, in which they described a double helix structure for DNA.Download the paper from Nature HERE.
Geological Time Scale In 1759, Italian geologist Giovanni Arduino (1714-1795) dated a letter to Professor A.Vallisneri the younger, in which Arduino proposed a classification of Earth's surface rocks according to four brackets of successively younger orders: Primary, Secondary, Tertiary and Quaternary.

From Today In Science History:In 1667, a classic paleontological paper by Nicolaus Steno was published by the Royal Society, London. His topic, Head of a shark dissected, represented the first such scientific paper to recognise that fossils were the remains of creatures who had died and subsequently had become petrified.

From Today In Science History:In 1868, Charles Darwin's book - Variation of Animals and Plants under Domestication - was published. He was 58. It is probably the second in importance of all his works. This was a follow-up work, written in response to criticisms that his theory of evolution was unsubstantiated. Show More Summary
As I was sorting through some old photos (circa 2000) I set aside some taken not all that long ago when the field station in DPP was the center for some cool palaeo-research. Above is outcrop right beside the field station that shows the contact between the Dinosaur Park and Oldman formations. Show More Summary
