Topic 26 The initial step in measuring dinosaurs tracks and trackways is to measure the size and shape of the individual fore (manus) and hind (pes) footprints and the angles and distances between them. TRUE Among the important measurements taken at trackways is the depth of the impression. FALSE The Linnaean system of nomenclature provides a uniform language of communications for scientists to refer to the same object or species. TRUE Theropod tracks generally have relatively long and narrow digit impressions, each digit ending with sharp, slender claw marks. TRUE Dinosaur tracks and trackways demonstrate that dinosaurs were diagonal walkers, meaning there is an angle between the mid-line of travel and successive right and left footprints. TRUE The term gastrolith refers to fossilized fecal material. FASLE The term “pentadactyl” refers to a foot or hand with how many digits? 5 Tracks of stegosaurs are extremely rare which suggests that stegosaurs were probably upland or dryland animals, rarely near wetland areas where tracks are preserved. TRUE The largest of the front prints of a sauropods are more than a meter long and deep as a bathtub. TRUE In some places bedding planes are completely covered with dinosaur tracks. They most often seem to occur around watering holes but may also be developed along migratory paths. These types of track occurrences are called DINOSAUR STOMPING GROUNDS. The heel of tridactyl theropods tracks is more rounded than the heel of tridactyl hardrosaurs tracks. FALSE Coprolites are trace fossils representing stones that were swallowed to assist in the digestion of food. FALSE Dinosaur tracks are best preserved in sediment that was moist but not too moist. TRUE Quadruped tracks are the most common type of dinosaur tracks, suggestion that most dinosaurs walked on four legs. FALSE The stride refers to the distance between successive steps, for example, the distance between the step of your right foot and your next step of the left foot. FALSE

Dinosaurs did not drag their tail or belly, indicating they walked upright with their limbs directly or nearly so under their body. TRUE Theropod tracks generally have relatively long and anrrow digit impressions, each digit ending with sharp, slender claw marks. TRUE More than one consecutive dinosaur track is a TRACKWAY. Dinosaur tracks have been found on all continents, except ANTARCTICA. Topic 27 The blood pressure required to pump blood from the heart to the head is a function of the distance and elevation of the head from the heart. TRUE Animals with a wide range of depth perception are more often ambush predators, lying in wait until their prey comes close and within their range of depth perception. FALSE Bacterial infection from bites and scratches may have been lethal to dinosaurs. TRUE The crest of lambeosaurines are hollow with a complex series of tubes inside, connecting to the nose and throats. TRUE In rare cases, internal organs many be represented as fossil molds or casts, even more
