True
Most ectotherms have sprawling postures
False
Ectothermic animals maintain a body temperature at 36-40 degrees C.
True
Endotherms require great motor and sensory control which is associated with larger and more complex brains.
False
The density of blood vessels in bone is higher in all ectotherms than in endotherms.
False
Mammals have a fully divided four-chambered heart and numerous fossil dinosaur hearts have only two chambers

False
Dinosaurs have complex scrolls of thin bone within the nasal cavity (turbinates) once covered with mucous membranes.
False
Most endotherms are egg-layers.
False
The optimum temperature of mammals is usually lower than those in the environment around them.
True
Endotherms require more food per body weight than is the case for ectotherms.
True
One dinosaur researcher, Dr. Bakker, finds the predator/herbivore dinosaur ratios similar to Cenozoic mammal (endothermic) populations and interpreted this as strong evidence for endothermy.
True
Endothermic predator- prey ratios should be lower than for ectotherms.
True
Most endotherms have an erect gait.
True
Endotherms require high blood pressure and rapid blood circulation to allow against oxygen and energy to circulate quickly through the body.
True
Ectothermic animals develop their heat from the external environment rather than metabolic sources.
True
Endotherms must eat more food per body volume than ectotherms because of their higher level of activity.
False
Growth rings occur in all living endotherms because of a seasonal pause in bone growth as food supplies are limited or climate unfavorable.
True
Many dinosaurs have lamellar-zonal bone (growth rings), a common characteristic of living ectotherms with seasonal pauses in their growth.
False
Large ectothermic dinosaurs would have more trouble maintaining a constant body temperature than smaller ones because of their large body volume.
True
The rate of metabolic reactions depends on the internal body temperature.
False
The Cleveland-Lloyd Dinosaur Quarry was first discovered by Princeton graduate student William Lloyd.
Earl Douglass
Who discovered dinosaur fossils near Jensen, Utah and developed it into Dinosaur National Monument?
False
No teeth marks were ever found among dinosaur bones in the Cleveland-Lloyd Dinosaur Quarry.
True
A Mexican sheepherder built a cabin of dinosaur bones at the site of Bone Cabin Quarry.
False
Roughly three-quarters of all dinosaur bones discovered at the Cleveland-Lloyd Dinosaur Quarry were those of plant-eating dinosaurs.
Como Bluffs
Bone Cabin Quarry is near (10 miles) this famous dinosaur locality.
True
Dinosaur National Monument was a dinosaur quarry for the Carnegie Museum prior to becoming a National Monument.
False
The Cleveland-Lloyd Dinosaur Quarry suffered a devastating loss in the 1960’s, when uranium exploration destroyed an estimated 100,000 dinosaur bones.
False
In 2001, University of Utah graduate student Terri “Bucky” Gates hypothesized that the great number of dinosaur bones found in the Cleveland-Lloyd Dinosaur Quarry is best explained by the presence of quicksand deposited by the runoff from a freshwater lake deposit.
True
In the reading “Fossil Wonders of the West”, Osborn mentions a theory of dinosaur extinction based upon egg pouching by mammals.
True
The exact boundaries of the bone beds at Cleveland-Lloyd Dinosaur Quarry are still unknown.
True
The Cleveland-Lloyd Dinosaur Quarry contains the densest concentration of dinosaur bones from the Jurassic ever discovered.
False
The Clevelend-Lloyd Dinosaur Quarry National Landmark is located in Cleveland, Ohio.
True
In the spring of 1898 Henry Fairfield Osborn discovered Bone Cabin Quarry.
True
The Cleveland-Lloyd Dinosaur Quarry National Landmark is still an active quarry.
True
Dinosaur National Monument is the largest and most spectacular display in the world of dinosaur bones still imbedded in the rocks that surround them.

_____ was the last of the great meat-eaters.
Gigantosaurus
____ lived about 95 million years ago and appears to edge out other theropods for the title of the largest meat-eater.
Troodon
_____ was probably the most intelligent dinosaur based on brain size relative to body size.
Argentinosaurus
_____ is believed to be the heaviest dinosaur.
True
Carcharodontosaurus is larger than tyrannosaurus rex.

_____ has the biggest and longest skull of any dinosaur.
Supersaurus
______ is believed to be the longest dinosaur.
Stegosaurus
______ is the dinosaur with the smallest head relative to its body size.
Pachycephalosaurus
_____ is the dinosaur with the thickest skull.
True
The most expensive dinosaur ever purchased is the Tyrannosaurus rex called “Sue”.
