1. Bird Vocab Quiz- Study Vocab!!!!

2. Kingdom AnimaliaPhylum ChordataSubphylum VertebrataClass 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. FishTwo Chambered Heart

5. Amphibian Heart- 3 Chambers

6. Reptilian Heart – 3 chambersCrocodile- incomplete 4

7. Fig. 48.28

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

9. Pelycosaurs • Synapsid reptiles from Pennsylvanian and Permian • 300-245 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 FossilThrinaxodon 250-245 mya Body divided into lumbar and thoracic regions

13. Transitional FossilCynognathus 245-230 mya May have been endothermic and gave birth to live young Smaller than a wolf

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

15. Early Mammals • Triassic • 220 MYA • Small • Hair • Mammary glands • Skin glands • Molar teeth Megazostrodon

16. Repenomamus robustusAte 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. Incissors

29. Canine

30. Premolars

31. Molars

32. Mammal Circulation

33. Fig. 31.12

35. Monotremes • Lay eggs • Incubate 12 days • Lick milk from mothers fur • Transitional species

36. Marsupials • Pouched mammals • Birth to tiny embryo • Embryo attaches to mother’s nipple to complete development

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

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

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. 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 Evolution of Placenta from Amniotic Egg

42. Mammal Classification • 14 major orders • Over 4,000 species • About half are rodents

43. Order Monotremata • Lays eggs • Young lick milk from mothers fur

44. Order Marsupiallia • Pouch

45. Placental: Order Insectivora • Sharp-snout • Small • Burrow underground • Eat insects

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

47. Echolocation

48. Smallest Mammal • Kitti’s hog-nosed Bat • Bumble bee size • 1.5 grams

49. Order Xenarthra • Toothless or peg like teeth

50. Order Carnivora • Large canine teeth • Teeth adapted to shear flesh
