New human ancestor species from Ethiopia lived alongside Lucy's species
A new relative joins “Lucy” on the human family tree. An international team of scientists, led by Dr. Yohannes Haile-Selassie of The Cleveland Museum of Natural History, has discovered a 3.3 to 3.5 million-year-old new human ancestor species. Upper and lower jaw fossils recovered from the Woranso-Mille area of the Afar region of Ethiopia have been assigned to the new species Australopithecus deyiremeda.
This hominin lived alongside the famous “Lucy’s” species, Australopithecus afarensis. The species will be described in the May 28, 2015 issue of the international scientific journal Nature.
Lucy’s species lived from 2.9 million years ago to 3.8 million years ago, overlapping in time with the new species Australopithecus deyiremeda. The new species is the most conclusive evidence for the contemporaneous presence of more than one closely related early human ancestor species prior to 3 million years ago. Read more.
The largest reconstructed Megalodon jaw in the world at 11 feet wide and 9 feet tall. It contains 182 fossil Megalodon teeth, up to 7 5/8 inches (one of the largest ever found). The majority of the teeth were collected by diver Vito Bertucci, who spent 16 years finding appropriately sized teeth and reconstructing the jaw. Most of the teeth were collected from North and South Carolina. He positioned the teeth based on a modern great white jaw, though there is debate whether this is the most accurate representation. This jaw was up for auction several years ago but doesn’t appear to have sold.
Because the jaws of sharks including the Megalodon are made of cartilage rather than bone which rarely fossilizes actual Megalodon jaws have never been found though their teeth can be fairly common. The Megalodon is believed to have reached nearly 60 feet in length, and would have had diet primarily of whales and other large marine mammals. They had a cosmopolitan (world wide) distribution, living in shallow water where their prey was plentiful. They went extinct somewhere around 2.5 million years ago. Well, unless you are truly gullible and believe in a bunch of made up evidence, CGI, and Discovery channel actors posing as scientists.
