Mammoth Dig Site

I am going to the Mammoth Dig Site in South Dakota next month.  At this site they have found Ice Age camels, llamas, giant short-faced bears,wolves, coyotes, prairie dogs, fish, mollusks, and many more!  They have found 52 North American Columbian Mammoths and 3 Wooly Mammoths - this is the only site in the world where both species have been found together.

Maiasaura

Maiasaura means "good mother lizard."  A maiasaura was 30 feet long and weighed 8000 pounds.  The name was chosen because she weighed so much she didn't sit on her nest, she just put leaves on her eggs so she wouldn't crack them trying to keep them warm.  There were as many as 10,000 maiasaura in a herd.


Here is a video of a song I really, really like from www.dinofun.com

Cryolophosaurus

Cryolophosaurus lived in Antarctica!  It is the first known dinosaur that lived on Antarctica.  Cryolophosaurus had an unusual sheetlike crest and no feathers and he ate meat.  He was 21 and a half feet long and weighed 1000 pounds.  He also had three fingers, three toes, and a neck about as big as the neck of a T. Rex.

Diplodocus

Diplodocus is 82 feet long and weighed 16 tons.  He is like a Brachiosaurus with a longer tail and smaller body.  He is slow and also uses his tail for balance.  Diplodocus is not very tall compared to Brachiosaurus, though, and must have had tough neck and tail bones.

Stegosaurus

Stegosaurus has two rows of bony plates on it's back head to tail.  He weighs five tons and was 30 feet long.  An adult African elephant weighs 6 to 8 tons.  Stegosaurus had a small skull and the spikes at the end of it tail were longer than it's skull.  His tail spikes were 3 feet long.

Kentrosaurus

Kentrosaurus was found in Tanzania, which is in Africa.  Kentrosaurus is like a Stegosaurus but half of it is plates and the other half is spikes.  Stegosaurus was all plates and Kentrosaurus also has a spike on each shoulder.  He was about an inch taller than a human and his beak wasn't as big as Triceratops'.
 

Einiosaurus

Einiosaurus is kind of like Triceratops but he has two big horns on his frill and a bigger, curved horn on his nose. He is smaller, too.  He is very weird looking and his legs are very strong looking.  His horn that curves is for defense, display, and attack.  He has a beak but Triceratops' beak curves at the end and his doesn't.
