Dinosaur Discovery

Sometimes it seems impossible to believe the amount of information that scientist can get from bones.  Scientists have discovered a fossilized skull of a new species (Sarmientosaurus musacchioi) of sauropod.  The skull belonged to a baby sauropod.  One that hatched and then died within weeks.

The little guy was about the size of a new-born baby (7 lbs) when it hatched.  A few weeks later it weighed 80 to 90 lbs.  Good thing out kids don’t grow that fast.  We’d never be able to carry them or carry the groceries to feed them.

From a scan of the skull of the baby the scientist figured out that the sauropod’s ear probably heard low-frequency sounds like elephants do today.  They also figured out that sauropods probably held their neck down, eating grass and other vegetation that was low to the ground rather than tree tops.

Happy Dinosaur Hunting.


Relationships of Birds

KQED Science has a very interesting article about bird relationships and their evolution.  Scientists have been decoding the genome of 48 species of birds and looking comparing the genes of them.  They have discovered a lot of interesting information.

Things like:

Birds use some of the same genes to sing that humans use to speak.

A lot of bird species developed shortly after the dinosaurs died.

The ancestor of birds lost it’s teeth before it evolved into a bird.

Take a look at the article.  I would like to know all the things they have learned.  The article just wet my curiosity.

Snaggletooth fossil in Maryland

Via WTOP.  A 15-million year old shark.

What has a duck’s bill, huge arms, and a hump?

A dinosaur!  Scientist only had arms before, now they have a couple of skeletons.  The arms are 8 feet long.

It is names Deinocheirus mirificus.  which means unusual horrible hands.

The BBC has more information here.  And NPR has another report here which has a little movie of how the dino might have looked and walked.
