Week 6 Flashcards
Deterrents
growths like horns, spikes deter predators from attacking for fear of injury
Or armour to make yourself difficult to eat and not worth the trouble
Or be very large
Crypsis
the ability to avoid detection using behaviour, camouflage or odor masking chemicals
hard to tell from fossils
but small dinosaurs probably did it more
Finite element analysis
technique to see if adaptations can do what they are hypotheses to do
simulates stress in an object
Side of head eye placements
send in herbivores that are prey they want to be able to see a lot
front of head eye placement
more seen in predators as this helps them identify and attack with their stereoscopic vision
-common in animals that can climb or fly
Ritualized agonistic combat
like pachycephalosaurs with their domed heads or dinosaurs with horns to fight without serious injury
monospecific bonebeds
large accumulation of fossil bones from the same species
-since the density is high it is most likely non random and needs an explanation like a group dying in a landslide
Non lethal face biting
agonistic behaviour done in crocodiles and tyrannosaurs
