The Vallesian age is a period of geologic time 11.6 9.0 Mya unit Ma within the Miocene used more specifically with European Land Mammal Ages . It precedes the Turolian age and follows the Astaracian age. The Turolian overlaps the Tortonian and Messinian ages. ref http paleodb.org cgi bin bridge.pl?action displayInterval&interval no 291 Paleo Database Vallesian ref The Vallesian was a crucial period for the evolution of the European terrestrial fauna. During the Middle Miocene, the highly diversified mammalian fauna of the European forests were replaced by the faunas of the Late Miocene, adapted to a dry climate and to an open terrain. The beginning of the period is marked by the appearance and dispersal of the early horse Hipparion throughout Eurasia. The so called Vallesian Crisis resulted in the extinction of several mammalian taxa characteristic of the Middle Miocene. The end of the Vallesian, and the beginning of the Turolian, brought the extinction in the west of faunas dominated by the bovid s and Giraffidae giraffids characteristic of the so called sub Paratethys Paratethyan or Greek Iranian province. ref cite web last Casanovas i Vilar first Isaac title The rodent assemblages from the Late Aragonian and the Vallesian Middle to Late Miocene of the Vall s Pened s Basin Catalonia, Spain publisher University of Barcelona year 2007 page 189 url http www.tdr.cesca.es TESIS UAB AVAILABLE TDX 1205107 162007 icv1de1.pdf ref References reflist geochronology stub Neogene Footer Category Pliocene ... more details

lead too short date July 2010 In biology , dactyly is the arrangement of wikt digit digits finger s and toe s on the hand s, Foot feet , or sometimes wing s of a tetrapod animal . It comes from the Greek language Greek word finger . Sometimes the ending dactylia is used. The derived adjectives end with dactyl or dactylous . As a normal feature Pentadactyly Pentadactyly from Greek language Greek pente five plus finger is the condition of having five digits on each limb. It is believed that all living tetrapods are descended from an ancestor with a pentadactyl limb, although many species have now lost or transformed some or all of their digits by the process of evolution . However, this viewpoint was challenged by Stephen Jay Gould in his 1991 essay, Eight Or Fewer Little Piggies . ref http www.stephenjaygould.org library gould eight piggies.html ref Despite the individual variations listed below, the relationship is to the original five digit model . Tetradactyly Tetradactyly from Greek tetra four plus finger is the condition of having four digits on a limb, as in many amphibian s, bird s, and theropod dinosaur s. Some mammals also exhibit tetradactyly for example pigs and the hind limbs of dogs and cats . Cartoon characters are commonly drawn with four digits on each hand foot as it s clearer to see than five. Tridactyly Tridactyly from Greek tri three plus finger is the condition of having three digits on a limb, as in the Rhinoceros and ancestors of the horse such as Protohippus and Hipparion . These all belong to the Perissodactyla . Some birds also have three toes, including emus , bustards , and quail . Didactyly Didactyly from Greek di two plus finger or bidactyly is the condition of having two digits on each limb, as in the Hypertragulidae and Two toed Sloth , Choloepus didactylus . In humans this name is used for an abnormality in which the middle digits are missing, leaving only the thumb and fifth finger, or big ... more details

The program reconstructs extinct animals. It is also called Mega Beasts .

The force and power of the neck muscles is shown by its hunting a horse in the beginning of the episode. To kill it, it drives its beak into the vertebral column, severing the spinal cord. Another example of this power is when the creature also killed a ground sloth, using the same method. At the end of the episode the crew was discussing extinction in the terror bird, two million years ago, and their conclusion was it was not well adapted. Episode 2 T rex Of The Deep In this episode, the mosasaur s are depicted as the main predators of the Cretaceous seas, competing with the giant sharks and plesiosaurs. It s also shown competing with and killing other mosasaurs. Episode 3 Biggest Killer Dino Spinosaurus was depicted as the apex predator at the time, killing Rugops , Carcharodontosaurus and Sarcosuchus . It fought with a Carcharodontosaurus and emerged victorious by smacking its face with a swipe of its claw. ref http dsc.discovery.com videos monsters resurrected biggest killer dino.html ref The Spinosaurus was shown being attacked by a Sarcosuchus .
