About The Class
Our two sixth grade classrooms are
taking part in Dr. Paul Sereno's dinosaur
expedition to Niger, and we are excited
to find out what discoveries there
might be this year.
Student Questions:
- Which was the last dinosaur
alive? Why was it the last one?
GRAY: They are in the air all around
you! Birds are actually a group
of dinosaurs that branched off quite
early in dinosaur history. They
are still alive and doing quite
well!
- How can you tell the
age of a dinosaur?
MILLER: Dating a dinosaur is tricky
because you can’t date the
actual dinosaur bones. Instead,
you must date the rocks that are
around them. There are two main
kinds of rocks that we deal with.
One kind is volcanic and the other
is sedimentary (rocks left over
by rivers and lakes). It is only
possible to date the volcanic rocks,
which is unfortunate because all
dinosaurs are found in sedimentary
rocks. However, if there are two
sets of volcanic rocks surrounding
the sedimentary rocks we find fossils
in, we know that the age is between
the ages of the volcanic rocks.
That is one way that we do it!
- How could all the dinosaurs
survive in the winter?
MILLER: Actually, a lot of dinosaurs
didn’t have to deal with winters
because they existed in more tropical
climates. We can only speculate
how any did, but if they were warm
blooded as some of us suspect, then
they would have been able to keep
themselves warm much as birds and
mammals do today.
- Why were some dinosaurs
meat-eaters and some plant-eaters?
SERENO: Most were either one or
the other. It is not common to find
animals, like ourselves, that can
eat both animals and plants. There
might have been a few small dinosaurs
that could have eaten both, but
they would have been very rare.
- Parent Question:
How can somebody become a dinosaur-bones
explorer?
GRAY: The best thing you can do
to become a dinosaur hunter is be
interested in dinosaurs! It also
helps to learn a lot about geology
and biology, but if you really love
dinosaurs, you are half way there!
