Why dinosaurs do not exists anymore ?

Question

Why dinosaurs do not exists anymore ?

Answer 1

Dinosaurs don't exist anymore because the earth was hit by a giant meteor (or maybe a deadly meteor shower) which wiped out the dino species. Creatures like frogs and early mammals survived because they were small and they seeked protection within the rocks which saved their lives :]

Answer 2

they became extinct [didnt they teach you that like in elementary school]

Answer 3

because, ice age had started.

Answer 4

They are too big to sustain their diet through draught.

Answer 5

The dinosaurs were almost certainly killed by the asteriod named Chicxulub the struck the Yucatan Peninsula about 65 million years ago.

Edit to respond to Fox below:

The water canopy is not a good scientific explanation for many many reasons.  For example, a vapor canopy would raise the atmospheric pressure to a point where all life on Earth would have died.

Answer 6

That is because only male dinosaurs existed! No females! Therefore, through time their race eventually disappeared... that also explains why archeologists found only a few dinosaur fossils... simply bec., they were only few!

Answer 7

To answer your question I will have to explain based on my beliefs which are that God created the heavens and the Earth and etc. etc. you get the picture. Here it goes.

Before the Great Flood the Earth was surrounded by a blanket of water. This water helped to absorb, deflect, and refract the sun's harsh rays that directly affect a unit of measurement that man calls time. You see, time is identified as the rate of decay.  So humans, as described in the Bible, lived for much much longer periods of time. Their lifespans were longer as well as the lifespans of the creatures around them. Mankind was not the sole benefactor of this curtain of water. Here is where you will find your answer:

Because of the blanket of water creatures live longer =

reptiles continue to grow until they die, AKA their growth NEVER ceases until death. = Because they lived so long, they were able to grow and grow and grow until they were creatures of great size and strength. = The fossils of these creatures were assembled and are known as dinosaurs.

Dinosaurs are nothing more than reptiles that lived for ages. However, after the great flood, the canopy of water that enveloped the Earth was poured down into what is now our oceans and seas. This is what is described as the flood gates opening. Ever since then we have not had the protection of the water from the sun's rays so we don't live as long as we use to. Neither do the animals. So reptiles don't live long enough now to grow to the size that would grant them the label of dinosaur.

I hope this answers your question ^_^

Answer 8

The Cretaceous–Tertiary extinction event was a large-scale mass extinction of animal and plant species in a geologically short period of time, approximately 65.5 million years ago (Ma). It is widely known as the K–T extinction event and is associated with a geological signature, usually a thin band dated to that time and found in various parts of the world, known as the K–T boundary. K is the traditional abbreviation for the Cretaceous Period derived from the German name Kreidezeit, and T is the abbreviation for the Tertiary Period (an historical term for the period of time now covered by the Paleogene and Neogene periods). The event marks the end of the Mesozoic Era and the beginning of the Cenozoic Era."Tertiary" is no longer recognized as a formal time or rock unit by the International Commission on Stratigraphy, the K-T event is now called the Cretaceous-Paleogene (or K-Pg) extinction event by many researchers.

Non-avian dinosaur fossils are only found below the K–T boundary and became extinct immediately before or during the event. A very small number of dinosaur fossils have been found above the K–T boundary, but they have been explained as reworked, that is, fossils that have been eroded from their original locations then preserved in later sedimentary layers. Mosasaurs, plesiosaurs, pterosaurs and many species of plants and invertebrates also became extinct. Mammalian and bird clades passed through the boundary with few extinctions, and evolutionary radiation from those Maastrichtian clades occurred well past the boundary. Rates of extinction and radiation varied across different clades of organisms.

Scientists theorize that the K–T extinctions were caused by one or more catastrophic events such as massive asteroid impacts or increased volcanic activity. Several impact craters and massive volcanic activity in the Deccan traps have been dated to the approximate time of the extinction event. These geological events may have reduced sunlight and hindered photosynthesis, leading to a massive disruption in Earth's ecology. Other researchers believe the extinction was more gradual, resulting from slower changes in sea level or climate.

Answer 9

Answer 10

The most widely accepted reason for their extinction is the asteroid impact that created the Chicxulub crater and coincides with their disappearance 65 million years ago.

This mass extinction is known as the Cretaceous–Tertiary extinction event. The nature of the event that caused this mass extinction has been extensively studied since the 1970s; at present, several related theories are supported by paleontologists. Though the general consensus is that an impact event was the primary cause of dinosaur extinction, some scientists cite other possible causes, or support the idea that a confluence of several factors was responsible for the sudden disappearance of dinosaurs from the fossil record.

The asteroid collision theory, which was brought to wide attention in 1980 by Walter Alvarez and colleagues, links the extinction event at the end of the Cretaceous period to a bolide impact approximately 65.5 million years ago. Alvarez et al. proposed that a sudden increase in iridium levels, recorded around the world in the period's rock stratum, was direct evidence of the impact.[102] The bulk of the evidence now suggests that a 5 to 15 kilometer (3 to 9 mi) wide bolide hit in the vicinity of the Yucatán Peninsula, creating the 170 kilometers (110 mi) wide Chicxulub Crater and triggering the mass extinction.

a eruption killed them all
