Description:
Peeking through the bushes, spotting their prey, stalking, trailing, and then leaping viciously onto...a rock? Okay so these people don't really hunt fossils, but they do a great job of finding them. Today's video is about fossil hunters.

The fossil hunter!! [Boy staring at a fossil]
- 00:27
Okay…maybe it's not the most exciting of all the hunters, but it has its moments!
- 00:30
A fossil hunter's goal is to, well …find…fossils.
- 00:34
Okay so it's not so much hunting as it is locating, but that's the word they're going with. [Person staring at fossil and fossil explodes]
- 00:39
Fossil locater just doesn't have the same air of mystery…
- 00:42
And realistically, whether it's dinosaur bones, an entire skeleton, or any other sort of evidence
- 00:47
of life from long, long ago, they're interested in finding it.
- 00:50
Fossil hunters come from all walks of life, and don't even need to be professionally-trained. [Fossil hunters together in a room]
- 00:55
Pick up a shovel, smear on the sunscreen, head out into the wilderness, and boom!
- 00:59
Instant fossil hunter!
- 01:00
Of course, it would help to have a general understanding of where you might want to look. [Girl reading a fossil hunting book]
- 01:04
Your parents' backyard probably isn't the best place to start…and they'll probably
- 01:07
be mad if you dig up the lawn. [Girl digs up lawn and parents appear]
- 01:09
Instead you should probably do a little research into dig sites and places you might be allowed
- 01:13
to dig.
- 01:14
Then you can get a-shovelin'.
- 01:16
No guarantees you'll actually find anything, but hey, at least it's good exercise! [Girl digs into the ground]
- 01:20
Once a fossil hunter actually does find a fossil, the first thing that must be done
- 01:25
is to determine whether or not the fossil really is, in fact, a fossil. [Person uses magnifying glass to inspect a fossil]
- 01:28
And that means calling in a true expert––a paleontologist – that's a scientist that
- 01:33
studies fossils.
- 01:34
The reason it's important to do this first is because a lot of the time, what looks to
- 01:38
be a fossil might just be a rock, or a really old baseball, or some weird paper-machie project
- 01:44
that got covered in a bunch of dirt and twigs. [Papermache project with dirt and twigs in a lab]
- 01:46
But if it is a real fossil, a paleontologist will know how to proceed next.
- 01:51
They'll probably call in special diggers called excavators, complete with special digging
- 01:54
tools, to carefully remove the fossils without harming them. [Coop discussing excavators]
- 01:58
And depending on the size of the fossil – y'know, if it's a complete T-Rex skeleton or something
- 02:02
– this could take a pretty long time. [Sloths digging up fossils and man waits]
- 02:04
Once a fossil is completely dug up, it must be carefully moved to a museum to be studied.
- 02:09
Naturally, bones that are millions of years old tend be pretty fragile, so things can [Man carrying a box of dinosaur bones]
- 02:13
get pretty tense while they're being moved around.
- 02:16
Once the bones are safely at the museum, they're handed over to experts who assemble them as
- 02:20
best they can in order to make them look like they were originally arranged. [Man assembles bones together]
- 02:24
In the case of a complete dinosaur skeleton, it can look pretty impressive.
- 02:29
And in the case of a just a single stray bone, well, it looks a little bit less impressive,
- 02:33
but we're sure your dog will appreciate it! [Dog snatches a bone from museum]
