question

True
answer

Most ectotherms have sprawling postures
question

False
answer

Ectothermic animals maintain a body temperature at 36-40 degrees C.
question

True
answer

Endotherms require great motor and sensory control which is associated with larger and more complex brains.
question

False
answer

The density of blood vessels in bone is higher in all ectotherms than in endotherms.
question

False
answer

Mammals have a fully divided four-chambered heart and numerous fossil dinosaur hearts have only two chambers
question

True
answer

Today feathers are only found on endothermic birds.
question

False
answer

Dinosaurs have complex scrolls of thin bone within the nasal cavity (turbinates) once covered with mucous membranes.
question

False
answer

Most endotherms are egg-layers.
question

False
answer

The optimum temperature of mammals is usually lower than those in the environment around them.
question

True
answer

Endotherms require more food per body weight than is the case for ectotherms.
question

True
answer

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.
question

True
answer

Endothermic predator- prey ratios should be lower than for ectotherms.
question

True
answer

Most endotherms have an erect gait.
question

True
answer

Endotherms require high blood pressure and rapid blood circulation to allow against oxygen and energy to circulate quickly through the body.
question

True
answer

Ectothermic animals develop their heat from the external environment rather than metabolic sources.
question

True
answer

Endotherms must eat more food per body volume than ectotherms because of their higher level of activity.
question

False
answer

Growth rings occur in all living endotherms because of a seasonal pause in bone growth as food supplies are limited or climate unfavorable.
question

True
answer

Many dinosaurs have lamellar-zonal bone (growth rings), a common characteristic of living ectotherms with seasonal pauses in their growth.
question

False
answer

Large ectothermic dinosaurs would have more trouble maintaining a constant body temperature than smaller ones because of their large body volume.
question

True
answer

The rate of metabolic reactions depends on the internal body temperature.
question

False
answer

The Cleveland-Lloyd Dinosaur Quarry was first discovered by Princeton graduate student William Lloyd.
question

Earl Douglass
answer

Who discovered dinosaur fossils near Jensen, Utah and developed it into Dinosaur National Monument?
question

False
answer

No teeth marks were ever found among dinosaur bones in the Cleveland-Lloyd Dinosaur Quarry.
question

True
answer

A Mexican sheepherder built a cabin of dinosaur bones at the site of Bone Cabin Quarry.
question

False
answer

Roughly three-quarters of all dinosaur bones discovered at the Cleveland-Lloyd Dinosaur Quarry were those of plant-eating dinosaurs.
question

Como Bluffs
answer

Bone Cabin Quarry is near (10 miles) this famous dinosaur locality.
question

True
answer

Dinosaur National Monument was a dinosaur quarry for the Carnegie Museum prior to becoming a National Monument.
question

False
answer

The Cleveland-Lloyd Dinosaur Quarry suffered a devastating loss in the 1960’s, when uranium exploration destroyed an estimated 100,000 dinosaur bones.
question

False
answer

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.
question

True
answer

In the reading \”Fossil Wonders of the West\”, Osborn mentions a theory of dinosaur extinction based upon egg pouching by mammals.
question

True
answer

The exact boundaries of the bone beds at Cleveland-Lloyd Dinosaur Quarry are still unknown.
question

True
answer

The Cleveland-Lloyd Dinosaur Quarry contains the densest concentration of dinosaur bones from the Jurassic ever discovered.
question

False
answer

The Clevelend-Lloyd Dinosaur Quarry National Landmark is located in Cleveland, Ohio.
question

True
answer

In the spring of 1898 Henry Fairfield Osborn discovered Bone Cabin Quarry.
question

True
answer

The Cleveland-Lloyd Dinosaur Quarry National Landmark is still an active quarry.
question

True
answer

Dinosaur National Monument is the largest and most spectacular display in the world of dinosaur bones still imbedded in the rocks that surround them.
question

In an old river bar
