Dinosaurs

Yes, it is believed so. some people argue/doubt of their existence. They are now fossilized in a museum.

Yes, South America has been a known location for dinosaur fossils. Some significant dinosaur fossils have been discovered in countries like Argentina and Brazil, providing valuable insights into prehistoric life on the continent.

No, the breakup of Pangaea occurred long before the mass extinction of dinosaurs. The main factor believed to have caused dinosaur extinction is an asteroid impact that occurred around 66 million years ago.

Dinosaurs became extinct around 65 million years ago due to a combination of factors, primarily believed to be a large asteroid impact and volcanic activity. Other factors such as climate change and disease may have also contributed to their extinction.

The earliest known dinosaur Eoraptor dates back to 230 years ago.

An recent fossil find in Madagascar however suggest that a species of pro-saurapod may have predated this by 2 or 3 million years at 233 years ago.

1. Paleozoic Era - 291 million years (542 - 251 Ma)
2. Mesozoic Era - 185.5 million years (251 - 65.5 Ma)
3. Carboniferous Period - 62.2 million years (359.2 - 299Ma)
4. Jurassic Period - 54.1 million years (199.6 - 145.5 Ma)

Dinosaurs have been extinct for approximately 65 million years.

Humans shared a common ancestor with monkeys about 6 million years ago, however Humans as such have only been around for roughly 40 thousand years.

The Jurassic period was followed by the Cretaceous period in the Mesozoic era. The Cretaceous period lasted from around 145 to 66 million years ago and ended with a mass extinction event that led to the disappearance of dinosaurs.

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.

Yes, there is evidence to suggest that earthquakes occurred during Jurassic times. The movement of tectonic plates and volcanic activity that were present during this period could have contributed to seismic events. However, the frequency and intensity of earthquakes during the Jurassic period would likely have been different from what we experience today.

The earliest reptiles known evolved around 312 million years ago, and looked a lot like lizards. However, they were not actually lizards. The oldest known lizard fossil dates to 220 million years ago, about the same time that dinosaurs evolved. That was during the Triassic period of the Mesozoic era.

Climate change from a large asteroid impact caused a dramatic drop in temperature, disrupting ecosystems and food chains. This led to the extinction of many plant and animal species, including the dinosaurs that could not adapt to the rapidly changing conditions.

Climate change is among the theories proposed to explain the extinction of the dinosaurs. Evidence includes fluctuations in global temperatures, changes in ocean chemistry, and the release of greenhouse gases. Fossil records also show a rapid decline in biodiversity around the time of the dinosaur extinction event.

85-75 million years ago falls within the Late Cretaceous period for Pteranodon, a genus of pterosaur that lived during this time. Pteranodons were flying reptiles that existed during the final age of dinosaurs.

Oviraptor dinosaurs were likely omnivores, meaning they primarily ate a diet of both plants and small animals. Their diet likely consisted of eggs, small vertebrates, insects, and plants based on the shape of their teeth and the fossil evidence found near their remains.

The Cenozoic era was not a subdivision of the Mesozoic era. The Mesozoic era is subdivided into the Triassic, Jurassic, and Cretaceous periods.

The fossils displayed in mueseums are usually plaster to prevent the originals from being damaged. The real ones are kept in a lab, most are at the American Mueseum of Natural History. There, they can be studied.

The likely contributors to the extinction event marking the end of the Mesozoic Era, known as the Cretaceous-Paleogene (K-Pg) extinction event, include a large asteroid impact on Earth, massive volcanic activity, and climate change. The asteroid impact at Chicxulub in present-day Mexico is considered a primary factor, causing widespread devastation and leading to the decline of many species, including the dinosaurs.

Many scientists believe that something other than asteroids have caused most catastrophic extinctions because some events, like the Permian extinction, show multiple stressors occurred simultaneously. The Deccan Traps volcanic eruptions coincide with the extinction of dinosaurs, suggesting a connection. Additionally, gradual environmental changes and feedback loops could have contributed to mass extinctions more than singular events like asteroid impacts.

There are three reasons; Antarctica wasn't at the south pole in the early Jurassic and during the Cretaceous, there was more carbon dioxide in the atmosphere which pushed up temperatures so that dinosaurs were able to survive. Finally, some dinosaurs were believed to be warm blooded and have feathers which are adaptations to survive colder temperatures - birds, particularly penguins, live at the south pole today and there is strong evidence that modern birds have evolved from dinosaurs.

1-1.8 million years ago was approximately 0.2-0.8 million years ago.

During the Jurassic period, the dominant plants were gymnosperms, including conifers, cycads, and ginkgoes. Ferns and horsetails were also prevalent, along with the early angiosperms. These plants contributed to the lush forests that characterized the Jurassic landscape.

Most dinosaurs died off about 65 million years ago.

Most life on Earth ended 65 million years ago during what is called the Cretaceous-Paleogene extinction event.

There is substantial scientific evidence of an asteroid or comet impact on Earth that caused or was the primary contributor to the extinction. A few scientists still hold other views, including a massive eruption of volcanoes.

no a dieses killed all the dinosaurs but we may never know if i am wrong or right No,

The reason for their ending may be because of the Flood that happened in the Bible,

If you look it up in Genesis you can read more.
