When it come to the biggest egg the world has ever seen , it ’s a close fight between reptilian and birds . The elephant shuttle claims the top topographic point with an bollock big enough to make the extant Struthio camelus ’s look average - sized , but “ The matter ” discovered by scientists in Antarctica was a tight second , and it came from a very unlike variety of animal .
count on to be around 66 million years ago , the football game - sizedegg of an ancient marine reptilewas found in Antarctica . It became the first known fossil easy - shell egg to have been left on the continent and is thought to have been put down by a mosasaur .
" It is from an animal the size of a large dinosaur , but it is completely unlike a dinosaur egg , " said track author Lucas Legendre , a postdoctoral researcher at the University of Texas Austin ’s Jackson School of Geosciences , in astatement . " It is most similar to the ballock of lizard and snake in the grass , but it is from a truly jumbo relative of these brute . "

It was previously believed that gargantuan marine reptile from the Cretaceous did not lay eggs , but the mysterious leather orb would seem to contradict that . scientist referred to the more than 28 - by-18 - centimetre ( 11 - by-7 - in ) stone - similar fossil simply as “ The Thing ” .
The “ visibly collapsed and folded ” thin - shelled egg is among the largest to have ever been described – 2d only to the elephant chick ’s egg – and its structure is like to most extant lounge lizard and Snake . That point towards whoever place it bear an ovoviviparous lifestyle whereby the egg develops within of the mother and hatches right away after being put .
The same was not true for the giantelephant dame . These flightless megafaunal birds were once widespread across Madagascar , weighing 500 kilogram ( 1,100 pounds ) and stretching 3 meters ( 10 foot ) tall . They were so large , it ’s recall one egg could feed an integral human family line .

Like birds today , the elephant wench ’s nut had a hard racing shell , unlike the subdued - shell football game our mosasaur bequeath in Antarctica . As the heavy eggs the planet ’s ever visualize , elephant bird eggs could measure 33 centimeters ( 13 inches ) long and with a fluent capacity of 8.5 liters ( 2.25 US gallons ) . According to theGuinness Book Of World Records , that ’s equivalent to seven ostrich eggs , 183 chicken ballock , or over 12,000 hummingbird eggs , making it the bombastic single cubicle have it off to have existed on Earth .
Both of these egg - laying behemoths are now out , and the title for with child ballock live today goes to the ostrich . According toDiscover Wildlife , the large eggs on track record come out of an ostrich in Sweden that unleash 2.589 kilo ( 5.7 pounds ) of shell - laden albumen .
Boiling that would no doubt have taken a spicy bit , but did you eff there ’s a way of life totell if an orchis is severely - boil without opening it ?
