The extinct genus Miracinonyx was extremely cheetah-like, but recent DNA analysis has shown that Miracinonyx inexpectatus, Miracinonyx studeri, and Miracinonyx trumani (early to late Pleistocene epoch), found in North America and called the "North American cheetah" are not true cheetahs, instead being close relatives to the cougar. Subspecies Although many sources list six or more subspecies of cheetah, the taxonomic status of most of these subspecies is unresolved. [according to whom?] Acinonyx rex—the king cheetah—was abandoned as a subspecies after it was discovered that the variation was caused by a single recessive gene. The subspecies Acinonyx jubatus guttatus, the woolly cheetah, may also have been a variation due to a recessive gene.
Stegosauruses had 17 bony plates that were embedded in its back. The arrangement of these plates was unknown until a 1992 Stegosaurus find in Colorado. The function of these plates is uncertain. The plates were made of bone which was not solid, but was filled with tube-like tunnels. The plates ran along the Stegosaurus' back and tail in two rows, and the plates alternated in alignment.
Manfred Korfmann, a German archeologist, has led excavations on the site believed to be Troy told of by legends for the past 16 years. He has said that if he were to meet someone who expressed belief that the Trojan War had happened in the site that his response would be, “why not” (Korfman 4)? Some of the results of the excavation have corresponded to the supposed date of the destruction of Troy. Evidence, for example skeletons and piles of sling bullets, support a possible conflagration. An issue brought up with accepting the city as Troy is that the town was “wholly insignificant” and “not a place worth fighting over” in the day in age associated with the war (Korfman 2).
When considering the Permian, it is important to understand that the events of the mass extinction relate to where the extinction occurred, on land or water. In previous decades, paleontologists had assumed that the extinction had occurred in a marine setting and that it had little to no impact on terrestrial organisms. However, just as there were significant extinctions realized in the oceans, there were also significant extinctions among vertebrates, plants, and insects. It is believed that this was the first and only mass extinction for insects ever. The Late Permian therapsids include the ancestors of mammals and are characterized for having mammal-like reptiles.
The origin of this wonderful mechanism is one of evolution's most durable mysteries. In 1861, just two years after Darwin published Origin of Species, quarry workers in Germany unearthed spectacular fossils of a crow-size bird, dubbed Archaeopteryx, that lived about 150 million years ago. It had feathers and other traits of living birds but also vestiges of a reptilian past, such as teeth in its mouth, claws on its wings, and a long,
Cave paintings are paintings that were found on cave walls and ceilings, and particularly refer to those of the prehistoric origin. The earliest non-concrete paintings in Europe go all the way back to the Aurignacian period, roughly about 32,000 years ago, they were seen in the Chauvet Cave in France. The particular purpose of the Paleolithic cave paintings was unknown. Some indications imply that they were not only decorations of living areas because the caves that discovered do not have marks of constant occupancy. They also often pinpointed in areas of caves that were not apparently available or accessible.
This lack of written evidence in Oceanic culture is much like that of the civilizations in Chapter 2 of Patterns. In Mexico, a large stone was discovered in 2006 that is thought to have Olmec writing on it. However, it is extremely hard to decipher. It was easier for myths to be transmitted verbally (Patterns, 128). Likewise, in Chapter 2, stones and clay tablets were also used in the Middle East since the late Paleolithic.
But this is not a view shared by Francesco d’Errico and João Zilhão who “claim that the Neanderthals developed the Châtelperronian tool industry in south-western France and northern Spain quite independently of the Cro-Magnons. They also believe that the Neanderthals ‘were capable of manufacturing the kinds of lithic [stone] and bone tools which have been found in Aurignacian levels’ (Palmer 2000, 190)”. To enforce their point, they highlight the fact “that there are Châtelperronian tools, especially some awls for perforating skins, from the Grotte du Renne, which are ‘decorated’ with sets of carefully made and regularly spaced notches … From this d’Errico and Zilhão conclude that the decoration was therefore part of an everyday and normal use of symbolism by the Neanderthals. Furthermore, it was an integral part of a late cultural development by them and not just something borrowed from the Cro-Magnons (Palmer 2000, 191)”. This use of art is a distinctly modern trait; the Neanderthals may well have had an artistic and
By the Upper Paleolithic (ending approximately 10,000 BCE), Neanderthal man had disappeared completely, and our ancestors were exhibiting fully modern behaviors such as making a wide range of even more sophisticated tools out of stone, bone, and ivory; hunting and fishing; and creating various forms of art such as figures and cave paintings. In the absence of a written language, early humans were still able to communicate and express themselves, and their spirituality, using pictures instead of words. They could record the locations of successful hunting grounds and invoke the animal spirits to aid them in their endeavors. Cave Paintings Cave paintings are the oldest form of Paleolithic art found to date, and can be found on almost every continent in the world. Until recently, the Chauvet cave paintings in France were believed to be the oldest, dating back to approximately 32,000 BCE; however, using carbon dating of the calcium deposits formed over the mineral-based paint, the cave paintings found in Spain’s are now believed to be over 40,000 years old [ (Than, 2012) ].
So it is more likely that loch ness monster is a plesiosaur. And this is the most important factor that people believe the loch ness monster is a plesiosaur. This evidence is doubted as a cheating. Because some scientists said it is impossible for loch ness to afford a plesiosaur. so the fossil may someone put there but not there originally.
