question

Most ectotherms have sprawling postures

answer

True

question

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

answer

False

question

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

answer

True

question

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

answer

False

question

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

answer

False

question

Today feathers are only found on endothermic birds.

answer

True

question

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

answer

False

question

Most endotherms are egg-layers.

answer

False

question

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

answer

False

question

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

answer

True

question

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.

answer

True

question

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

answer

True

question

Most endotherms have an erect gait.

answer

True

question

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

answer

True

question

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

answer

True

question

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

answer

True

question

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

answer

False

question

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

answer

True

question

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

answer

False

question

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

answer

True

question

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

answer

False

question

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

answer

Earl Douglass

question

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

answer

False

question

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

answer

True

question

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

answer

False

question

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

answer

Como Bluffs

question

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

answer

True

question

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

answer

False

question

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.

answer

False

question

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

answer

True

question

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

answer

True

question

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

answer

True

question

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

answer

False

question

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

answer

True

question

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

answer

True

question

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

answer

True

question
