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.

Hermit Crabs

Hermit crabs are decapods.  That means they have ten feet or 5 pairs of legs; not all the legs can be found by just looking.  Unlike true crabs, they don’t grow their shell.  They find one that fits and carry it around until they outgrow it.  How do they find the right size shell?  Watch this video and see the Crab Line.

Otherwise, enjoy the hermit crabs in the wild.  They live best there.

Steppe Bison Mummy from Siberia

A steppe bison mummy was found a couple of years ago.  It is about 9,300 years old.  I lived with the Mammoths in the Ice Age.  It was kept frozen until scientist could do an inspection (necropsy) on it.  You can read more here.
