1 Bird Vocab Quiz- Study Vocab!!!!

2 Kingdom Animalia Phylum Chordata Subphylum Vertebrata Class Mammalia
SZ2- Students will explain the evolutionary history of animals over the geological history of Earth. Mammals evolved from early synapsid reptiles

3 Primitive Chordate

4 Fish Two Chambered Heart

5 Amphibian Heart- 3 Chambers Fig

6 Reptilian Heart – 3 chambers Crocodile- incomplete 4

7 Fig

8 Synapsids Animals with one skull opening behind eye socket
Located in the temporal region

9 Pelycosaurs Synapsid reptiles from Pennsylvanian and Permian
MYA Body close to ground Legs away from body Canine like teeth Dimetron

10 Therapsids Before dinosaurs
Evidence suggests Mammals evolved from therapsids Body raised off the ground Limbs more under the body Teeth differentiated into 3 types Lystrosaurus

11 Cynodonts “dog tooth” Lumbar ribs reduced or absent
Well developed secondary palate Lower jaw reduced to one bone Thrinaxodon Cynognathus

12 Transitional Fossil Thrinaxodon
mya Body divided into lumbar and thoracic regions

13 Transitional Fossil Cynognathus
mya May have been endothermic and gave birth to live young Smaller than a wolf

14 Cladogram of Synapsids
Cynodonts Mammals Therapsids Molars, hair, glands Pelycosaurs Reduced ribs, 1 jaw bone Limbs under body, different types of teeth Canine like teeth Synapsid reptiles

15 Early Mammals Triassic 225 MYA Small Megazostrodon

16 Repenomamus robustus Ate Dinosaurs

17 Kingdom Animalia Phylum Chordata Class Mammalia Have fur/hair
mammary glands Viviparous- Give birth to live young (except monotremes) Length of time in uterus - gestation period Extended parental care 4 chambered heart endothermic

18 Mammalian Anatomical Adaptations
Muscular Diaphragm Specialized teeth Seven cervical(neck)vertebrae Outer ear Well developed brain- Largest cerebrum Sweat glands 7. Diphyodont teeth Two sets 8. Heterodont teeth Different shapes and functions

19 Basic Mammal

20 Lion

21 Rhinoceros

22 Gorilla

23 Chimpanzee

24 Chimp and Human

25 Bat

26 Same bones, different stance


28 Incisors

29 Canine

30 Premolars

31 Molars

32 Mammal Circulation

33 Fig Fig

34 Humans Reunite with Animals They Raised

35 Mammal Classification
14 major orders Over 4,000 species About half are rodents


37 Monotremes “cloaca” Lay eggs Incubate 12 days
Lick milk from mothers fur Transitional species Ex. Echidna, duck-billed platypus

38 Marsupials Pouched mammals Birth to tiny embryo
Embryo attaches to mother’s nipple to complete development

39 Marsupials and Monotremes in Australia
Triassic Period Mammals evolved Pangea Jurassic Period Monotremes and marsupials migrated to southern pangea Cretaceous Period Pangea breaks up

40 Placental Mammals Placenta nourishes embryo Long gestation period
22 months for elephant Most successful group of mammals

41 Placental Mammals Competitive advantage over monotremes and marsupials
Better nutrition from placenta Less vulnerable to predators More advanced at birth

42 Evolution of Placenta from Amniotic Egg
Reptile Chorion Oxygen from air Amnion Provides private pond Yolk Sac Food for embryo Allantois Store urinary waste Mammal Chorion Form placenta to get oxygen & food from mothers blood Amnion Provides private pond Yolk sac Temporarily make RBCs Allantois Form umbilical cord


44 Placental: Order Insectivora
Sharp-snout Small Burrow underground Eat insects

45 Order Chiroptera Only Flying mammals Elongated fingers Echolocation
Ex. bats Importance- Seed dispersal Pollination Control insects

46 Echolocation

47 Smallest Mammal Kitti’s hog-nosed Bat Bumble bee size 1.5 grams

48 Order Xenarthra Toothless or peg like teeth

49 Order Carnivora Large canine teeth Teeth adapted to shear flesh

50 Order Rodentia Chisel-like incisor teeth Continuously grow
Largest order

51 Order Cetacea “large sea animal”
Front limbs modified into flippers No hind limbs Marine

52 Whales Blue whale 100 feet long, 120 tons Loudest animal– 188 dB
9 story building Loudest animal– 188 dB Sound travels 100’s of miles


54 Blue Whale Baleen whale Eats krill Heart weighs 1000 pounds
Tiny crustaceans 400 pounds/day Heart weighs 1000 pounds Size of a Volkswagen Endangered species

55 Grey Whale

56 Migrates 12,500 miles

57 Grey Whale 50 feet long 35 tons Baleen whale Endangered species
Sift mud Endangered species

58 Killer Whale

59 Breaching

60 Killer Whale 12,000 pounds Eat fish, squid, seals and whales
200 pounds/day Swim 30 mph

61 Humpback Whale

62 Order Pinnipedia “fin feet” Limbs modified for swimming
Marine carnivores Seals, sea lions, walrus

63 Order Proboscidea Tusks Largest living land mammal

64 Order Artiodactyla “even toe” Two or four toes
Giraffes, impalas, moose, bison, cows

65 Order Perissodactyla “odd toed” One or three toes Horses rhinos

66 Order Primata Opposable thumb Binocular vision Fingernails usually
Mammary glands reduced to one thoracic pair Most intelligent group of animals

67 The End

68 Evolution Change over time
Which Chordate class do you think has more advantages/adaptations to survive changing times? Which classes have disadvantages? Which Chordate classes can you see evolutionary similarities in so far?
