Lessons 1&2
The scientific study of the remains of ancient animals and plants.
Not existing anymore; having no living members.
Extinct
Only eats meat.
Carnivore
Is a pterosaur a dinosaur?
No
Eats both meat and plants.
Omnivore
The preserved remains, or traces of remains, of ancient organisms.
Fossil
An extinct group of reptiles.
Dinosaurs
Only eats plants.
Herbivore
What plesiosaur had a long neck and small head?
Elasmosaurus
The only fossil for this extinct marine animal we have recovered is its many teeth.
Megaladon
Where was the Megalosaurus first discovered?
Oxfordshire, England
Why were dinosaurs so big?
-Pneumatic Bones
-More vegetation/oxygen to consume
What key part of identifying a species tells us if it was a herbivore or carnivore?
Teeth
an extinct group of marine reptiles
plesiosaur
What country was the Argentinosaurus found in?
Argentina
An indent mark formed by life preserved in rock.
Impression
What dinosaur was commonly called "duck-billed dinosaur"?
Parasaurolophus
What can we assume about a fossil with flat teeth.
It was a herbivore.
an extinct group of flying reptiles
pterosaur
What dinosaur was believed to be highly intelligent?
Velociraptor
The process of organisms being exposed to minerals and turning into a stonelike substance over a period of time.
Petrification
Bones with an air-filled cavity inside them.
Pneumatic Bones
Amateur paleontologists reported finding a complete Tyrannosaurus rex skeleton in a cornfield in Iowa, USA. They said they saw the bones sticking up out of the mud and were so excited to find the white bones that they immediately started digging them up. They found 50 bones in total and laid them out. They reported that it was a small T. rex, only 2.74 meters (9 feet) long. They were very excited to have found a T. rex skeleton, or did they?
No! The first problem is that fossils are not likely to be found in Iowa farmland because there are no rock formations, such as cliffs or mountains. Second, fossils found in this area are not completely white because they turn into petrified rock, which is generally gray, black, or brown. Finally, a complete skeleton of a T. rex would contain 380 bones, not 50. The bones in the story could not have been the bones of a T. rex.
What three types are classified in the group Reptilia?
the process of fossilization that takes place as mineral water fills space in an organism and hardens into rock over a period of time
Permineralization
