How Many Dinosaurs Are There?
Palaeodiversity and formation counts: redundancy or bias?. 2015. M. Benton, Palaeontology.
In a new study published this week, Professor Mike Benton has explored how knowledge about dinosaurs has accumulated over the past 200 years, since the first dinosaur was named in 1824.
His research does not answer the question once and for all, but it suggests that strong caution is needed with some popular methods to 'correct' the fossil record. From: http://phys.org/news/2015-08-good-bad-fossil-dinosaurs.html#jCp

Died This Day: Lorenz Oken
Lorenz Oken (Aug. 1, 1779 - Aug. 11, 1851) was a German naturalist who offered early evolutionary ideas and stimulated comparative anatomy. He theorized (incorrectly) that the skull was a modified vertebra, but formed some fundamental concepts which stimulated further thought from later scientists.
In Die Zeugung, he discussed “the infusoria”—elementary units of living organisms—into which all flesh can be broken down. Higher animals, he proposed, consisted of constituent animalcules. Entities, whether plants or animals, became organisms by the fusion of these primal animals. Those elements lose all individuality and create a higher unity. From Today In Science History

Premiered This Day: Dinosaurus! (1960)
Dinosaurus! (1960) was directed by Irvin Yeaworth and produced by Jack H. Harris. The movie poster is pretty bland so I’m presenting the cover for the comic adaptation instead.
The film is most notable for the fact that the 'Brontosaurus' model and miniature jungle from the film were used for an episode of the The Twilight Zone (1959) ("The Odyssey of Flight 33). Wikipedia
