Were dinosaurs warm or cold blooded has been a long time debated issue. Scientist believe dinosaurs were much like modern day reptiles, cold blooded, and others believe dinosaurs were much like mammals and others birds, warm blooded. Dinosaurs are creatures that lived on Earth around 251 million years ago. Dinosaurs lived in the Mesozoic Era. This era contained three separate subsections: the Triassic Era, the Jurassic Era, and the Cretaceous. When the Mesozoic Era ended, most or a majority of the dinosaurs were extinct due to a catastrophic event that is still unknown to us today. Dinosaurs walked in an upright position, some dinosaurs used two legs, other used four to walk and move around their environments. Dinosaurs came in an array of sizes. Humans were able to examine the characteristics of this dinosaurs via their fossils. The fossils were found nearly every continent. …show more content…
Dinosaurs are closely related to the modern birds, who are warm blooded. New evidence has showed that dinosaurs have been known to be cold blooded but evidence has showed differently. New evidence shows dinosaurs regulated their body temperature from an internal stance than using the environment to help regulate their body temperature. Dinosaurs has homologous features of other animals of their time. Research supports that dinosaurs are warm blooded. Cold and warm blooded terms are terms used throughout science to explain the way an animal regulate their body temperature. Terms used to explain warm and cold blood animals are: endothermic, ectothermic, homoeothermic, and poikilothermic. These four terms help to describe what warm and cold blooded mean. Endothermic animals regular their body temperature from the inside their
The evidence clearly indicates that this theropod had lung and respiratory mechanics similar to that of a crocodile—not a bird. There was evidence of a diaphragm-like muscle separating the lung from the liver, much as you see in modern crocodiles. These observations suggest that this theropod was similar to an ectothermic reptile, not an endothermic bird. Did feathered dinosaurs exist?
Were dinosaurs warm blooded or cold blooded: Before beginning the argument we have to understand the term endothermy (homeotherms) and ectothermy (poikilotherms) : Endotherms: (endo, “inside”) , animals exhibit endothermy ,when they warm their tissues by the production of metabolic heat. Homeothermy : animals that thermoregulate by physiological means (rather than just by behaviour) Were dinosaurs warm or cold blooded ? Ectotherms : (ecto , “outside”) , animals exhibit ectothermy when thermal conditions outside the bodies of these animals determine their body temperature. Poikilothermy : body temperature of the animal is determined by equilibration with the thermal conditions of the environment and varies as environmental conditions vary.
Including human, most mammals and birds are homeotherms that regulate their body temperature internally to keep it relatively
What are the major theories explaining the disappearance of the dinosaurs? Dinosaurs lived between 230 and 65 million years ago. Dinosaurs then disappear as if they were never on earth. There are many theories in the world about the death of the dinosaurs. Archaeologist discovers the the bones of dinosaurs from different time periods.
Land organisms have the ability to regulate their body temperatures in order to survive in the environment and scientists are digging deep in research and observation in order to figure out how the honey bees function in different temperatures of their surroundings. Different variations in temperature of the environment are a facing threat to most land animals and more specifically flying organisms. Because there is a zone in which contains the most compatible temperature for them to have maximum ability to function properly, they will not most likely cannot survive in extreme temperatures. However, the structures and their bodily system such as the proteins and enzymes that provide a solution. It has little effect on the drastically changing
Ray Bradbury used figurative language to describe the Tyrannosaurus Rex in “A Sound of Thunder. ’’ Ray Bradbury compared the legs to pistons, this means that the Tyrannosaurus Rex has strong legs. He compared it’s eyes to ostrich eggs, this means that the dinosaur has big eyes. He also compared muscles to thick ropes, this means that the dino has big thighs.
They were believed to have become tree dwelling in the later species. The discovery of the anklebones is substantial because paleontologists had only the animal’s teeth and jaws to study. The anklebones were found in the
T Natrix tells Wart a old story about the dinosaurs. There were two types of dinosaurs, a bloodthirsty carnivorous dinosaur and a peaceful herbivore. The carnivorous dinosaurs eventually went extinct after losing a war with the herbivores, and eating themselves because of starvation and their bloodthirsty needs. Eventually, there was one herbivore left. Man came across this dinosaur, and killed it, because he recognized all dinosaurs as killers.
To be more specific, the dinosaurs live in the era with warmer overall temperature. Even in polar regions, the wether is suitable for animals that are not endothermic
The discovery of this mammal was proof that mammals had lived alongside the dinosaurs. It gave scientist a small glimpse into ancient mammal species. Chapter 6– Questions
Title Researchers and scientists have constructed extensive research on dinosaur’s extinction. Speculation instead of real evidence seems common in most theories about the dinosaurs’ extinction. However, Jay Gould’s essay “Sex, Drugs, and the Extinction of Dinosaurs” is the complete opposite of speculation over evidence. Rather, Gould uses the mix of persuasive techniques, such as rhetorical questions, logos, along with profound evidence to not only disapprove of other theories but convince readers of his place on the dinosaur’s extinction.
Once they are in the past and see the Tyrannosaurus Ray Bradbury uses imagery to explain what the dinosaur looks like. The Tyrannosaurus was described as, “...thirty feet above half the trees, a great evil of god, folding its delicate watchmaker’s
In the website Universe Today, it says “The fossil record not only shows the dinosaurs disappearing, but also numerous species of the era.” So not only the dinosaurs are extinct, but other species were too. The meteor was very destructive. The meteor that killed the dinosaurs was called the Chicxulub crater. The Chicxulub crater killed reptiles but are not extinct.
Reptile scales act as a protective layer to help prevent water loss from their bodies. Mammals are warm-blooded animals and reptiles are cold-blooded animals. Mammals are endothermic which means they can produce and control their body heat internally. Reptiles are ectothermic, they use their resources such as the sun to get
Introduction I. Snakes are reptiles. They are cold-blooded animals with the amazing ability of raising and lowering their body temperatures to adapt to the environment. II. They are distinctively known for their long elongated body and scaly skin. III.
