BBC : The KT Event - The evidence for the mass extinction of the Dinosaurs
February 27, 2008
A look at the scientific evidence for the Cretaceous-Tertiary mass extinction event.
From the Earth & Life series. We see how many different scientific disciplines including Paleontology,
Astronomy & Geology have found a mass of evidence for a cataclysmic extinction event about 65.5 million years ago.
The Chicxulub crater, initially found by gravity readings of Oil exploration, is revealed as the probable “smoking gun” of a massive impact.
(the latest scientific evidence points to a multiple impact event and even it’s possible origin the asteroid 289 Baptistina with it’s breakup causing the formation of
Tycho crater on the moon as well as Chicxulub) This impactor radically altered the earths atmosphere and killed of vast amounts of marine and plant life as well as
a great many of the larger life forms including the Dinosaurs.
Also includes a short film at the end examining three scientific “keywords” Catastrophism, Waterfalls & Limestone

[RS] BBC - Walking With Dinosaurs Special Sea Monsters [Doc]
Sea Monsters was a BBC television program which used computer-generated imagery to show past life in Earth's seas. It was made by Impossible Pictures, the creators of Walking with Dinosaurs, Walking With Beasts and Walking With Monsters.
In this series, British wildlife presenter Nigel Marven is shown travelling to seven past seas in Earth's history and scuba diving there, in order of dangerousness with the most dangerous last. He travels in a white sail/motor boat roughly 24 m (80 ft) long named The Ancient Mariner. His time-travelling device is not mentioned or shown. He uses a scuba set with a fullface mask so he can talk underwater to produce the commentary. He performs some dives using a strong shark cage, which is spherical to make it harder for large sea creatures to bite it.
