Asked in Dinosaurs, Extinct Animals
What do scientists believe caused the extinction of the dinosaurs?
Scientists have many theories about what caused the extinction of dinosaurs. Below are thoughts on some of the most common theories: Since about 90% of dinosaurs were herbivores (plant eaters), it was thought that when an asteroid hit earth and many tons of dust was thrown into the atmosphere that the result was a "long night" due to the lack of sunlight that was able to reach earth, the plants died out and without a food source, so did the dinosaurs. It could also...

What is extinction angle control?
extinction angle control is a scheme of forced commutation for power factor improvement in phase controlled convertors/rectifiers. In this scheme the firing angle is adjusted in order to get the desired output or load voltage. By varying the value of extinction angle we can get the desired load voltage and current waveform.......submitted by abhimanyu(sunny) ...
What happens when an animal becomes extinct?
When an animal becomes extinct, there is little to no chance that science (as we know it) can bring this animal species back again. The world will have lost another unique and interesting animal species. When an animal becomes extinct, it also upsets the foodchain, which can disrupt the life cycle of other species. ...
What was the first dinosaur with feathers?
This is a tricky question for many scientists for two reasons. The first being that feathers cannot be fossilized with the bone. We have to look for their imprints in the surrounding rock, and even those are rare. The second is that the line between dinosaur and bird is very thin. If you mean all dinosaurs including birds, then primitive fliers such as Archaeopteryx had the first feathers. If not, then a Early Cretaceous genus called Sinosauropteryx is the first known non-avian...

How much is a trilobite?

How did the passenger pigeon get its name?
The term 'passenger' was taken from the French word 'passager' which means 'to pass by'. Passenger pigeons took quite a while to 'pass by' because in the 1800's and before, their flocks were so huge. This is probably where the name came from. ...
Asked in Birds, Dodos, Extinct Animals
Could the dodo bird fly?

Asked in Extinct Animals, Tasmanian Tigers
How did the thylacine live?
Prior to their extinction, Thylacines (also known as Tasmanian tigers) lived in grasslands and bushland of Tasmania. There is also fossil evidence indicating that they lived on the Australian mainland. The Thylacine was a dasyurid, or carnivorous marsupial, which preyed on mammals smaller than itself. Being a marsupial, the female had a pouch. The Thylacine had a gestation period of one month, and the young spent another 3-4 months continuing their development in the pouch. ...
Is there a zoo that repopulates animal life of almost extinct animals?
Answer Although this might be meant as the goal of most zoos, it is unfortunate that some, especially smaller zoos, care more for money than they do for their animals. By keeping them confined to small cages with little room to move, while taking the profits made from saving space, for more animals. On the other hand there are wildlife rehabilitation centres which save injured wildlife, then return them when they are healthy again. Answer The San Diego Zoo has a Center for Conservation...
