How long did the plesiosaur live? Plesiosaurus is an extinct marine reptile which lived approximately 135 million to 120 million years ago – from the Early to the Middle Jurassic Period. It was first discovered in the winter of 1823 by fossil hunter Mary Anning in Western Europe.
Is mosasaurus a plesiosaur? Many of the so-called ‘dinosaur’ remains found on New Zealand are actually mosasaurs and plesiosaurs, both being Mesozoic predatory marine reptiles.

how can animals go extinct? – Similar Questions
do zoos prevent extinction?
Zoos do a lot for conservation. There are dedicated species survival programs which have helped species come out from the brink of extinction, good examples of that being the black-footed ferrets, the red wolves, the Przewalski’s wild horse, and the California condors.
is giant sea turtles extinct?
Archelon is an extinct marine turtle from the Late Cretaceous, and is the largest turtle ever to have been documented, with the biggest specimen measuring 5 m (16 ft) from head to tail and 2,200 kg (4,900 lb) in body mass.

when did the scimitar oryx become extinct?

what causes the permian extinction?
Warming of the Earth’s climate and associated changes to oceans were the most likely causes of the extinctions. At the end of the Permian Period volcanic activity on a massive scale in what is now Siberia led to a huge outpouring of lava.
how did the mass extinction happen?
What causes mass extinctions? Past mass extinctions were caused by extreme temperature changes, rising or falling sea levels and catastrophic, one-off events like a huge volcano erupting or an asteroid hitting Earth. We know about them because we can see how life has changed in the fossil record.

A cloned Pyrenean ibex was born on July 30, 2003, in Spain, but died several minutes later due to physical defects in the lungs. This was the first, and so far only, extinct animal to be cloned.
What are the positive effects of extinction?
In effect, a mass extinction cleans the slate, creating new evolutionary niches which promote a wide range of species, increasing biodiversity, competition and in some cases increasing complexity in organisms as they try to carve out their niche in the new world. We are an example of the aftermath of mass extinctions.
Is there dark matter everywhere?
Since dark matter is everywhere, it should be in our Solar System as well. So why haven’t we seen it yet? According to a large amount of evidence, the overwhelming majority of the Universe is made out of some mysterious type of mass that we’ve never directly measured.
Is the extinction of a species good?
In some ways, yes. An estimated 99 percent of the species that have ever lived on Earth are now extinct, and many died out as part of five different mass extinctions [source: Gray and Ensor]. New species evolved to fill the space left by extinct species and increased the biodiversity of our planet.
Why do pink dolphins exist?
The dolphins are actually born gray and slowly turn pink as they age. Male dolphins are strikingly pinker than their female counterparts; the coloration thought to be a product of scar tissue resulting from rough games or fighting over conquests.
Are cheetahs functionally extinct?
Cheetahs have faced extinction at least two times in the past after their populations were reduced, leading to inbreeding. Once again, cheetahs face extinction today, due in part to surviving the past threats of extinction.
Can cloning bring back extinct animals?
Cloning eventually could bring back extinct species such as the passenger pigeon. For now, the technique holds promise for helping endangered species including a Mongolian wild horse that was cloned and last summer born at a Texas facility.
Is there a limit to mutations ark?
Yes, up to three mutations can happen for an offspring, with +2 wild levels on a stat one color change for each mutation. Multiple mutations can target the same stat, so you could see +4 or +6 wild levels on a single stat. Can creatures be bred infinitely to increase their stats?
Did an asteroid cause the Permian extinction?
Most scientists agree a meteor impact, called Chicxulub, in Mexico’s Yucatan Peninsula, accompanied the extinction of the dinosaurs 65 million years ago.
How long do Night Furies live?
They have a lifespan of 30 and mature at 8-9. OK so if we do lifespan/age until fully grown on Komodos and Crocs and find the average, we get 4.65. I said earlier that it’s likely that Night Furies become fully grown at 11-14 so if we multiply that by 4.65, we get 51-65 as their lifespan.
Are sea turtles still going extinct?
Nearly all species of sea turtle are now classified as endangered, with three of the seven existing species being critically endangered. WWF is committed to stopping the decline of sea turtles and works for the recovery of the species.
What is a functionally extinct species?
A “functionally extinct” organism is one that may have a few individuals still living but will never recover (think Martha the passenger pigeon or Lonesome George the Pinta Island tortoise). Some organisms are “extinct in the wild,” meaning they can no longer be found in the areas they once inhabited.
