Paleozoic Vertebrates and Plants:  Paleozoic Vertebrates and Plants Chapter 13 Part 2 Chapter 12&13 summary:  Chapter 12&13 summary Review of Paleozoic vertebrates:  Review of Paleozoic vertebrates Jawless fish Jawed fish Eventually to amphibians Slide4:  Can amphibians take over the world? Dependence on water for reproduction Amniote egg:  Amniote egg Egg hatch as mini adult Skip larval stage With amniote egg: reptiles Oldest known reptile - Mississippian:  Oldest known reptile - Mississippian Oldest reptile - Mississippian:  Oldest reptile - Mississippian Reptile differences: Skull, jawbone better for chewing Pennsylvanian reptiles Hylonomus 30 cm long:  Pennsylvanian reptiles Hylonomus 30 cm long Small for agility Easier to keep warm/burrow Easier to heat by sun Pennsylvanian reptiles:  Pennsylvanian reptiles Trapped in trees? Made dens there? Slide10:  Reptiles appear in Carboniferous Permian: reptiles dominate & amphibians displaced Why so successful? Advanced: Reproduction Movement Jaws/teeth Permian reptiles:  Permian reptiles Dominant group: Pelycosaurs (finbacks) Herbivores and carnivores Dominant group: Pelycosaurs (finbacks):  Dominant group: Pelycosaurs (finbacks) How can you tell herbivore vs. carnivore? Finback reptile fossil:  Finback reptile fossil Purpose of sail to: Scare off attacker? Protection? Sexual display? Thermal regulation? Permian reptiles:  Permian reptiles Pelycosaurs extinct in Permian Succeeded by therapsids Mammal-like reptiles Permian therapsids:  Permian therapsids Small-medium animals Start of mammal features Fewer skull bones Larger lower jaw Teeth with different functions More vertical legs Hair? Permian therapsids:  Permian therapsids Small-medium animals Start of mammal features Fewer skull bones Larger lower jaw Teeth with different functions More vertical legs Hair? Permian therapsids:  Permian therapsids Small-medium animals Start of mammal features Fewer skull bones Larger lower jaw Teeth with different functions More vertical legs Hair? Permian therapsids:  Permian therapsids Small-medium animals Start of mammal features Fewer skull bones Larger lower jaw Teeth with different functions More vertical legs Hair? Permian theraspids:  Permian theraspids Endothermic? (warm-blooded) Maintain constant body temperature Why important? How to prove/disprove? End of Paleozoic:  End of Paleozoic 90% of reptiles were therapsids 2/3 of reptiles wiped out in Permian extinction Plants were less affected Two groups of plants:  Two groups of plants Nonvascular: mosses, liverworts, fungi need water for survival. Vascular plants: tissue system to move water, nutrients (most land plants) Earliest land plants: nonvascular Evolved into vascular plants Earliest vascular plant spores: Ordovician:  Earliest vascular plant spores: Ordovician Nonvascular: mosses, liverworts, fungi need water for survival. Vascular plants: tissue system to move water, nutrients (most land plants) Earliest land plants: nonvascular Evolved into vascular plants What do plants need to develop to be vascular?:  What do plants need to develop to be vascular? Tissue to transport water/nutrients Tissue to support plant body Avoid desiccation with outer wall Protection from UV Roots to collect water/nutrients from soil Roots to anchor plant Leaves for photosynthesis Which came first?:  Which came first? Land plants or land animals? Oldest land plant, Silurian:  Oldest land plant, Silurian Simple leafless stalk with spores Seedless vascular plants Amphibian of plant world Early Devonian landscape:  Early Devonian landscape Early Devonian: low-growing plants Late Devonian: 30 foot tall plants Devonian ferns:  Devonian ferns Early Devonian: low-growing plants Late Devonian: 30 foot tall plants Devonian plants:  Devonian plants First: seedless vascular plants Seedless plants need water for reproduction Next: seed plants Why seeds? Slide29:  Seed plants: late Devonian Seedless vascular dominate Carboniferous Why plants important in Carboniferous? Carboniferous swamps:  Carboniferous swamps 70% of coal made from seedless vascular trees Carboniferous flowerless seed plants:  Carboniferous flowerless seed plants Drier, higher land Paleozoic plants:  Paleozoic plants By end of Permian: Flowerless seed plants take over Why seed plants not seedless? Climate drier and warmer Carboniferous plants:  Carboniferous plants Glossopteris Seed fern Paleozoic plant evolution:  Paleozoic plant evolution
