Hi,
டயனோசர்களின் கடைசி நொடிகள் | Last Moment of Dinosaurs #dinosaur #vaanveli

Impact Event: The most widely accepted theory is that around 66 million years ago, a large asteroid or comet, estimated to be about 6 miles (10 kilometers) in diameter, collided with Earth. This impact event is believed to have occurred in what is now the Yucatán Peninsula in Mexico and created the Chicxulub crater. The energy released in the impact would have caused massive fires, tsunamis, and a "nuclear winter" effect, with debris and soot blocking sunlight for an extended period.

Immediate Consequences: The impact would have caused massive wildfires across the globe, releasing a tremendous amount of soot and gases into the atmosphere. This would have led to a sudden drop in temperatures, making it difficult for many species, including the dinosaurs, to survive.

Climate Change: The impact and subsequent environmental changes caused by the impact led to a drastic cooling of the Earth's climate. This would have disrupted ecosystems, causing a decline in plant life, which, in turn, would have affected herbivorous dinosaurs and the predators that relied on them.

Mass Extinction: The combination of factors, including extreme temperature fluctuations, lack of sunlight, and ecological disruption, likely resulted in a mass extinction event. Many species, including the non-avian dinosaurs, went extinct during this time.

Surviving Species: While the non-avian dinosaurs went extinct, some groups of animals, such as birds, small mammals, and reptiles, managed to survive and eventually evolve into the diverse life forms we see today. Birds are the only living descendants of the dinosaur lineage.

Hi, See the Top 10 Extinct Animals.

Gorgonopsia:
Gorgonopsia is an extinct clade of sabre-toothed therapsids from the Middle to Upper Permian roughly 265 to 252 million years ago. They are characterised by a long and narrow skull, as well as elongated upper and sometimes lower canine teeth and incisors which were likely used as slashing and stabbing weapons.

Dickinsonia:
Dickinsonia is a genus of extinct organism that lived during the late Ediacaran period in what is now Australia, China, Russia and Ukraine, most likely a basal animal. It is one of the best known members of the Ediacaran biota. The individual Dickinsonia typically resembles a bilaterally symmetrical ribbed oval.

Haikouichthys:
Haikouichthys is an extinct genus of craniate that lived 518 million years ago, during the Cambrian explosion of multicellular life

Astraspis :
Astraspis is an extinct genus of primitive jawless fish from the Ordovician of Central North America including the Harding Sandstone of Colorado and Bighorn Mountains of Wyoming. It is also known from Bolivia.

Pneumodesmus newmani:
Pneumodesmus newmani is a species of myriapod that lived during the late Wenlock epoch of the Silurian period around 428 million years ago.

Nothosaurus :
Nothosaurus is an extinct genus of sauropterygian reptile from the Triassic period, approximately 240–210 million years ago, with fossils being distributed from North Africa and Europe to China. It is the best known member of the nothosaur order

Scutosaurus :
Scutosaurus is an extinct genus of pareiasaur parareptiles. Its genus name refers to large plates of armor scattered across its body. It was a large anapsid reptile that, unlike most reptiles, held its legs underneath its body to support its great weight

Dimetrodon :
Dimetrodon is a genus of non-mammalian synapsid that lived during the Cisuralian age of the Early Permian period, around 295–272 million years ago. It is a member of the family Sphenacodontidae.

Jaekelopterus :
Jaekelopterus is a genus of predatory eurypterid, a group of extinct aquatic arthropods. Fossils of Jaekelopterus have been discovered in deposits of Early Devonian age, from the Pragian and Emsian stages.

Titanichthys :
Titanichthys is an extinct genus of giant, aberrant marine placoderm from shallow seas of the Late Devonian of Morocco, Eastern North America, and possibly Europe. Many of the species approached Dunkleosteus in size and build.
