The Debate Over Dinosaur Nostril Positioning

Regarding the position of the dinosaur's nostrils, you need to place the nostrils of the dinosaur model. This seems to be a fairly simple problem, but since it is a topic that has been studied recently, it is safe to create an anatomically correct dinosaur model. Amniotic fluid animals (populations containing reptiles and synaptosomes in the Triassic, dinosaurs) have large nostrils, but their nostrils are made up of meat and cartilage, so they should be preserved in fossil records There is hardly any. 1996).

Researchers have discussed the temperature regulation of dinosaurs for decades, but the new controversy began with the research of the Science Journal in 2014, stating that dinosaurs may be middle class. In fact, previous studies on dinosaur energy rates, energy expenditure, and teeth have also found evidence that they are warm blooded animals. Researchers say that the answer to this question will not only cover scientific journals but, in contrast, a more complete depiction of how dinosaurs survive and die. In order to solve the controversy, researchers studied the bones of fossil dinosaurs. In these bones there is a growing circle like a tree ring. It is believed to indicate growth rate or growth rate of animals. Researchers compare the growth rate of dinosaurs with the growth rate of endangered animals and living animals and dinosaurs are between growth continuum between warm-blooded and cold-blooded animals I found out.

According to the Phalanx number (the number of fingers in the finger), the hands of the dinosaurs and the birds are essentially different. The result may challenge the consensus that birds are descendants of dinosaurs, so this is an important and highly controversial field of research. Embryologists and some paleontologists who oppose bird dinosaurs have counted the number of birds for a long time based on many studies on the development of eggs II - III - IV. This is based on the fact that, in most amniotic fluid animals, the number first formed in the hand of five fingers is the number IV, which forms the long axis. Therefore, embryologists determined the long axis of birds as IV and the number of survivors as II - III - IV. The advanced Tetanurae hand fossil seems to have the number I-II-III (some of the genus Abeleroida also has a reduced number IV)
