Most ectotherms have sprawling postures

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

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

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

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

Today feathers are only found on endothermic birds.

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

Most endotherms are egg-layers.

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

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

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.

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

Most endotherms have an erect gait.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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