Article of the Day
Ornithoprion is an extinct genus of cartilaginous fish. Its only species lived during the Moscovian age. Its fossils are preserved in black shales from the Midwestern United States. Ornithoprion's genus name, which is Greek for 'bird saw', was inspired by its bird-like skull and the saw-like appearance of the teeth in the lower jaw. The specific name honors the German zoologist Oscar Hertwig. Ornithoprion had a unique projection of its lower jaw termed the mandibular rostrum, which was covered by a beak of fused bony scales. It inhabited shallow, seasonal marine and brackish water environments. The rounded shape of Ornithoprion's teeth suggests that it hunted hard-shelled invertebrates, and bite marks and damage to some of its fossils indicate that it was fed on by other carnivores. Ornithoprion was small relative to other members of its order, with a cranium length of up to 10 cm (3.9 in) and an estimated body length of up to approximately 91 cm (36 in). (Full article...)

Why you should extend your general knowledge:
There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.
As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
