Animals with one skull opening behind eye socketLocated in the temporal region9

PelycosaursSynapsid reptiles from Pennsylvanian and Permian 300-245 MYABody close to groundLegs away from bodyCanine like teeth

Dimetron10TherapsidsBefore dinosaursEvidence suggests Mammals evolved from therapsids Body raised off the groundLimbs more under the bodyTeeth differentiated into 3 types

35MonotremesLay eggsIncubate 12 daysLick milk from mothers furTransitional species

36MarsupialsPouched mammalsBirth to tiny embryoEmbryo attaches to mothers nipple to complete development

37Placental MammalsPlacenta nourishes embryoLong gestation period22 months for elephantMost successful group of mammals

38Placental Mammals

Competitive advantage over monotremes and marsupialsBetter nutrition from placentaLess vulnerable to predatorsMore advanced at birth39Marsupials and Monotremes in AustraliaTriassic PeriodMammals evolvedPangeaJurassic PeriodMonotremes and marsupials migrated to southern pangeaCretaceous PeriodPangea breaks up

42Mammal Classification14 major ordersOver 4,000 speciesAbout half are rodents

43Order MonotremataLays eggsYoung lick milk from mothers fur

44Order MarsupialliaPouch

45Placental: Order InsectivoraSharp-snoutSmallBurrow undergroundEat insects

46Order ChiropteraOnly Flying mammalsElongated fingersEcholocationEx. batsImportance-Seed dispersalPollinationControl insects

47

Echolocation48Smallest Mammal

Kittis hog-nosed BatBumble bee size1.5 grams49Order XenarthraToothless or peg like teeth

50Order CarnivoraLarge canine teethTeeth adapted to shear flesh

51Order RodentiaChisel-like incisor teethContinuously growLargest order

52Order CetaceaFront limbs modified into flippersNo hind limbsMarine

The EndEvolutionChange over timeWhich 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?
