ENSIPEDIA.ID, Jember – Dinosaurs are 1 of the very interesting ancient animals to do investigation mainly because they have a gigantic body that is inversely proportional to modern animals. Unfortunately, no dinosaur fossils have ever been discovered in Indonesian territory.
So why have dinosaur fossils under no circumstances been identified in Indonesia? To find out extra, it’s a fantastic idea to focus on the heritage of the dinosaurs initially
The phrase dinosaur was popularized by Sir Richard Owen which will come from the Greek which means “denos” which indicates huge, terrible, sturdy and the word “sauros” which usually means lizard. Dinosaurs are estimated to have lived on earth all over 245 million many years back, which implies they lived in the Mesozoic period. The Mesozoic period is divided into three phases, namely the Triassic, the Jurassic and the Cretaceous.
Dinosaurs so much can’t be identified with certainty how quite a few. According to John Very long, a paleontology professor at Flinders College, there are presently all over 900 legitimate dinosaur species. Legitimate in this circumstance is that the existence of the species can be confirmed by researchers and has adequate fossil evidence to be declared as a species.
Dinosaurs are imagined to have develop into extinct after a meteor shower that transpired 65 million yrs back when a big asteroid 15 kilometers in diameter struck Earth. The asteroid assault had a shock pressure equivalent to 10 billion Hiroshima bombs. The strength of this shock is the precursor to the formation of the Chicxulub crater below the Mexican Yucatan Peninsula.
As we know, dinosaurs lived in the Mesozoic period in which there ended up a few phases, particularly the Triassic, Jurassic and Cretaceous. The Triassic lasted from about 252 million yrs to 201 million yrs ago, the Jurassic from about 210 to 145 million a long time ago and the Cretaceous which took put 145 to 66 million several years in the past.
In reality, all through these three phases, the mainland of Indonesia is nevertheless below the ocean and was shaped only about 30 million many years in the past. Of all the areas of Indonesia, only the island of Borneo was component of Eurasia in the Mesozoic era. However, it is not but feasible to find dinosaur fossils owing to the geological conditions of the island of Borneo, which is mainly a peat lavatory, and the need for substantial costs to conduct the research.
This is strengthened by the concept that dinosaurs averted the equator or equator in the Mesozoic period. This is mainly because the equatorial location is extremely scorching and dry. In addition, the equatorial area incorporates a lot of carbon dioxide which can lead to organic fires.
