PREMIERED THIS DAY (1915): THE DINOSAUR & THE MISSING LINK. It features the earliest work of a young Willis O'Brien who would go on to bring King Kong to life. Watch the film thanks to The Library of Congress. youtu.be/so9Exr5Ammo?...

BORN THIS DAY: ELKANAH BILLINGS (May 5,1820-June 14,1896): Canada’s first paleontologist. His boss Sir William Logan wrote him (1869): "Your constant absence from the office is a worrying annoyance, particularly as I have reason to suspect that it does not arrive from rheumatism."

More for May the 4th: colleague Dr David West Reynolds standing at the bluff where Luke looked down on Mos Eisley. In the distance you can just see the palm trees that mark the location of the Well of Souls dig site from Raiders of the Lost Ark. Was this Tunisian adventure really 30 years ago?!

For May the 4th: Me discovering the origin Krayt Dragon prop skeleton in Tunisia back in the early 90’s. The film quarry abandoned this & all the Star Wars props when they left. After I found them (and left them in place!), collectors followed in my footsteps and scoped them up. Hello Ebay!

BORN THIS DAY: JOSEPH BARRELL (Dec 15, 1869–May 4, 1919: Proposed that sedimentary rocks were produced by the action of rivers, etc (1917); used radioactive dating to reinterpret Earth's age to billion years; argued that severe climate drove the evolution of air-breathing vertebrates

Died This Day: Joseph Leidy (Sept 9, 1823 - April 30, 1891). The Father of American Vertebrate Paleontology described the holotype of Hadrosaurus foulkii, the 1st American mostly complete dinosaur. He also mentored a young E.D. Cope and pointed he and Marsh to the rich fossil resources of the West

DIED THIS DAY: LOUIS DOLLO (Dec 7, 1857–April 19, 1931). Dollo researched the Iguanodons found in 1878 in a mine at Bernissart, Belgium. He is also noted for ‘Dollo's Law of Irreversibility’ which states that a complex structure once lost in evolution never reappears exactly in its former state

Died This Day: Erasmus Darwin (Dec 12, 1731 – April 18, 1802). Grandfather of Charles Darwin, he was a philosopher/naturalist who formulated one of the first theories of evolution in his ‘Zoonomia’ (1794-1796). In it he discussed how life evolved from a single common ancestor

The Canadian fossil record supports anagenesis in Triceratops (Ornithischia, Ceratopsia)
Evolution of the ceratopsid dinosaur Triceratops has been hypothesized to have proceeded anagenetically, with the geologically older Triceratops horridus having directly given rise to the younger Tric...

DIED THIS DAY: JAMES HUTTON (June 3, 1726 – Mar 26, 1797). Scottish geologist known as the Father of Modern Geology for helping establish geology as a modern science. His Principle of Uniformitarianism states that modern geological features are the result of continuing natural processes over time.

Premiered This Day (1970): When Dinosaurs Ruled The Earth. Hammer’s follow up to One Million Years B.C. (1966) lacked Ray Harryhausen’s animated dinosaurs, but did feature excellent stop-motion work by Jim Danforth and David Allen, and arguably a better script by English SF author, J.G. Ballard.
