Evolution Of Pterosaurs

Yes, I believe that they did have pygmy goats, chickens, and pigs. The selected animals have to be able to produce enough quantities of proteins and at the same time, able to consume small amount of food sources. Many animals are also able to clean the environment and their waste can also be process as fertilizer for the plants. I believe that pigs consume too much food sources in comparison with the amount of meat that the animal is able to produce. A combination of fish is a great

Scientists say reptiles evolved from amphibians 340 million years ago. The first reptile was an insect eater. Reptiles were more adaptable and able to

In this article according to the scientist they have found many links between Rusingoryx and hadrosaur dinosaurs. Palaeontologists have found skull of ancient wildebeest, hollow dome that makes a crest on top of the animal 's skull.

First, the author notes that since modern reptiles are cold-blood and have very low metabolism, ancient reptiles such Pterosaurs could not provide enough energy for powered flight due to their low body metabolism. The professor refutes this statement by referring to the fact that fossil remaining of Pterosaurs proved that, similar to warm-blood animals like birds, these animals had

The Titanosaurus is a newly discovered dinosaur well more like found in the year of 2012. The Titanosaurus was found by a ranch owner in Argentina, by the name you could probably figure out that the dinosaur is huge it's 65 feet tall and 131 feet long and weighs about 77 metric tons (170,000 lbs). but that's not all because the ranch owner called a museum to tell them he found some fossils. The American Museum Of Natural History found out that the animals only been underground for little less than a year, it's so recently found that it doesn't have a species name yet. The American Museum Of Natural History also used new technologies were used on this where the bones were actually laser scanned and prototype from the laser again. This went from

Now, there are a lot of questions related to wether or not large theropods like Tyrannosaurus rex for example were totally covered in a dense coat of feathers or where totally scally creatures. Some say being so large it would have been a disadventage fot a "fluffy" T-rex, because it will have been suffering of overheating, but feathers are very different from the hair of mammals, the structure of feathers allow large birds like the ostrich to discipate the heat from the body if the external temperature is so hot (very similar to the mecanisms that modern afrinac elephants have with their large ears!). So large meat eating dinosaurs would have lived very well with a dense coat of feathers even if their environment was very hot (of course the case of a "fluffy" T-rex is still in debate, some think thet T-rex would have beel partially covered in proto-feathers and scales, but wheter of both scenarios, large theropods would have developes mecanisms for losing heat, see link below the

The Arthopleau was the largest known land-invertebrate of all time. They were 1- 8 ½ feet long and are related to millipedes and centipedes. Since there were no fossil mouth parts to ever be found, scientists thought for a while that they were carnivores. But the recent discovery of plant’s pollen in the animals guts ( ew, I know) have suggested that the Ortho Pleau was actually a herbivore.

Zhenyuanlong Suni is a winged dinosaur from the Yixian Formation in China. The fossil found is the only one on record currently. Zenyuanlong Suni was discovered in June 2015, and the orginal analysis was done by Dr. Stephen Brusatte and Junchang Lü. Unfortunately not much is known about our dinosaur. Luckily the lone fossil found has almost been perfectly preserved, it even included traces of feathers from its wings. We found that it was highly unlikely that Zhenyuanlong Suni was capable of having powered flight due to its underdeveloped muscle structure yet it had very large wings. Some of its ancestors before could fly (powered flight) and we also find dinosaurs closely related that the capability of powered flight. This poses the question, what were the wings used for? The wings are very large and are aerodynamic, they just lack the muscle needed for powered flight.

BOOM! BOOM! BOOM! The Triceratops, it is coming!! What are you thinking about? What was it’s last meal? Is it hungry? I hope it doesn’t eat me. Well, it’s last meal was probably cycads or bushes/leaves close to the ground. You got it, they’re herbivores. An herbivore is an animal that only eats plant. The answer to the second question just depends on when it has eaten. You cannot exactly predict when an animal or anything will be hungry, if you could do that, it would be pure A-MAZ-ING! But most of the time, it doesn’t matter if it a triceratops hungry, no, they are almost always on the lookout for food, even if they just ate. Oh yeah, I almost forgot about the third part. It may be intimidating, but as long as you hide, NOT BEHIND BUSHES!!

Tales of the mighty reptilian beasts known as Dragons can be found all over the world from all throughout history. The origin of dragons is unknown, although there are legends that can be traced to approximately 5,000 B.C. (Owens). These legends have appeared independently all over the Earth, with variations of course, but still enough similarity to be clearly identified as the same creatures. Although the modern world no longer fears dragons as the dangerous creatures lurking in the hidden corners of the world, should their existence be dismissed entirely? The Earth has held many equally monstrous creatures, from the 60 ft. shark Megalodon (Patton) to the 50 ft. snake Titanoboa (Gowan) or even the recently discovered 130 ft. titanosaur (currently unnamed) (Frizell). Compared to other creatures that have roamed the Earth, dragons may seem no less believable however, (I) although dragons appeared independently and simultaneously across the globe, they did so with many physical and behavioral differences (II) nowadays dragons have faded into mythology,

Any lift that would come out of the winged features would generate drag causing a loss in acceleration. 1 However, just as the Arobreal theory was supported by Archaeopteryx, the Cursorial theory is also strongly supported by this specimen. Archaeopteryx demonstrates a complete set of conical teeth and claws that were sharp and resembling the specimens relative Ornitholestes, a known predaceous animal.3 The Archaeopteryx also resembles therapods with a reversed hallux, hindlimb, and pelvis.3 Even though this theory is supported using fossil evidence, it does have some problems which have lead to the development of theories such as the WAIR

At the time of their rule, there were fearsomely large birds, giant pachyderms, and ferocious dinosaurs, which shared the land. However, even though some of these other beasts were identical in size or larger

The discovery that birds evolved from small carnivorous dinosaurs of the Late Jurassic was made possible by recently discovered fossils from China, South America, and other countries, as well as by looking at old museum specimens from new perspectives and with new methods. The hunt for the ancestors of living birds began with a specimen of Archaeopteryx, the first known bird, discovered in the early 1860s. Like birds, it had feathers along its arms and tail, but unlike living birds, it also had teeth and a long bony tail. Furthermore, many of the bones in Archaeopteryx's hands, shoulder girdles, pelvis, and feet were distinct, not fused and reduced as they are in living birds. Based on these characteristics, Archaeopteryx was recognized as

In this case, the dragon is a subject to theories. It wasn’t until 1841 that English scientist Richard Owens suggested that the group of “newly discovered animals be called “dinosaurs,” which literally means terrible lizards. Throughout the next few decades, the first artist depictions of dinosaurs were actually comical when compared to what we can scientifically discern today. How then, do pottery, linens, cave paintings, and written descriptions of “dragons” from 2,000 to 4,000 years ago depict dinosaurs better than what science could muster in the mid-1800’s?” (History of Dragons). Scientist might be able to prove the existence of dragons to be false, but their reality in our modern day life is real. Lizards such a the komodo dragon are an example. As said, they grow to be very large. In fact, many people to this day believe that the dragons still exists. “The belief in dragons was based not just in legend but also in hard evidence — or so it seemed. For millennia no one knew what to make of the giant bones that were occasionally unearthed around the globe, and dragons seemed a logical choice for people who had no knowledge of dinosaurs.” (Radford 4). However, it will take some looking to find solid proof of dragons, that doesn’t mean they do or do not exist. Many people have their own beliefs on what they do and don’t

Dental microwear studies suggest that the diet of H. habilis was flexible and versatile and that they were capable of eating a broad range of foods, including some tougher foods like leaves, woody plants, roots, berries and some animal tissues (birds and insects), but that they did not routinely consume or specialize in eating hard foods like brittle nuts or seeds, dried meat, or very hard tubers.
