Crocodiles originated in the Sahara desert??




Crocodile ancestors found in Sahara

-----------------------------------------------------------------------

"Fossils of five ancient relatives of modern-day crocodiles have been found in the Sahara Desert.
Three of the fossils, discovered by University of Chicago research Paul Sereno, represent newly named species. Sereno dug up the fossil remains in a series of expeditions beginning in 2000.
All of the prehistoric crocs lived about 100 million years ago in the southern super-continent known as Gondwana, when the region that is now the Sahara featured dinosaurs and grassy plains criss-crossed by rivers.
"These species open a window on a croc world completely foreign to what was living on northern continents," Sereno said in a statement.
The new croc fossils are described in the journal ZooKeys and will feature in the November issue of National Geographic magazine and in a special airing Saturday on the National Geographic Channel."

Gondwana (or Gondwanaland) was a composite continent, made up of South America, Africa, Madagascar, Antarctica, India, other parts of South Asia, and Australia.  At one time it even included Florida and most of Southern Europe.
Gondwanaland is named after the Upper Paleozoic and Mesozoic formations of the Gondwana district of central India, which display a number of shared geologic features (the "Gondwana beds").  In the late nineteenth century, on  the basis of comparative geological evidence, the Austrian geologist, Edward Suess, suggested that the continents of Africa, South America, Australia and India were once part of a single supercontinent, which he called "Gondwanaland".
Science tells us that the Continents of Australia, India, South America, Africa, and Antarctica, existed together as a separate landmass as long as 650 million years ago.  And as these continents only began to break up some 130 million years ago, this great supercontinent had a life of around 520 million years; making it perhaps the most important geological structure of the last billion years.

This is what Gondwanaland looked like:

It is fascinating that a species such as the crocodile appears to have originated in a desert isn't it?  Crocodiles are reptiles and reptiles can live in both land and water, however, it is obvious that crocodiles need water to survive. So how did these ancestors of the crocodiles get their water living in a desert??

Thoughts worth thinking about

"Our subconscious minds have no sense of humor, play no jokes and cannot tell the difference between reality and an imagined thought or image. What we continually think about eventually will manifest in our lives."-Sidney Madwed



Laws alone can not secure freedom of expression; in order that every woman and man present their views without penalty, there must be spirit of tolerance in the entire population.- Albert Einstein Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around. - Leo Buscaglia



A person's true wealth is the good he or she does in the world. - Mohammed



Our task must be to free ourselves... by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty. -Albert Einstein



The best way to find yourself, is to lose yourself in the service of others. - Ghandi



The unselfish effort to bring cheer to others will be the beginning of a happier life for ourselves. - Helen Keller



Aim for success, not perfection. Never give up your right to be wrong, because then you will lose the ability to learn new things and move forward with your life. Remember that fear always lurks behind perfectionism. Confronting your fears and allowing yourself the right to be human can, paradoxically, make yourself a happier and more productive person. - Dr. David M. Burns



Life is as dear to a mute creature as it is to man. Just as one wants happiness and fears pain, just as one wants to live and not die, so do other creatures. -His Holiness The Dalai Lama



Mankind's true moral test, its fundamental test (which lies deeply buried from view), consists of its attitude towards those who are at its mercy: animals. And in this respect mankind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it. -



Milan Kundera, The Unbearable Lightness of Being



The worst sin towards our fellow creatures is not to hate them, but to be indifferent to them. That's the essence of inhumanity. -George Bernard Shaw

Ego's trick is to make us lose sight of our interdependence. That kind of ego-thought gives us a perfect justification to look out only for ourselves. But that is far from the truth. In reality we all depend on each other and we have to help each other. The husband has to help his wife, the wife has to help the husband, the mother has to help her children, and the children are supposed to help the parents too, whether they want to or not.-Gehlek Rinpoche Source: "The Best Buddhist Writing 2005 pg. 165

The hostile attitude of conquering nature ignores the basic interdependence of all things and events---that the world beyond the skin is actually an extension of our own bodies---and will end in destroying the very environment from which we emerge and upon which our whole life depends.
