  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

  27. Incissors

  28. Canine

  29. Premolars

  30. Molars

  31. Mammal Circulation

  32. Fig. 31.12

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

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

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

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

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

  38. 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

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

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

  41. Order Marsupiallia • Pouch

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

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

  44. Echolocation

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

  46. Order Xenarthra • Toothless or peg like teeth

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