What terrestrial advantages do Seed Plants have over earlier land plants?

Refer to the slides attached below to answer the following questions.

  1. Seed Plants

a)What terrestrial advantages do Seed Plants have over earlier land plants?

b)How does the nutritional quality of Seed Plants affect the physiology of their herbivores?

 

  1. Flowering Plants

a)What advantages do Flowering Plants have over Seed Plants?

b)How is the reproduction of Flowering Plants tied to herbivores?

c)Open spaces today are dominated by which group of flowering plant that was mostly absent from Mesozoic habitats?

 

  1. Mesozoic mammals

How has the traditional view of Mesozoic mammals changed given recent discoveries?

 

  1. Multituberculates

a)Which common modern placental mammal group do multituberculates closely resemble in both form and function?

b)“Multi’s” were a successful group from the middle Jurassic (~180 Ma) to the late Eocene (~30 Ma). How many millions of years did they persist? Assuming your answer to (a) radiated after the K-Pg extinction, which group was on Earth longer?

 

  1. Pterosaurs

a)What bones of the front limb were modified in the pterosaur wing?

b)What features did pterosaurs convergently share with birds?

 

  1. Pseudosuchians

a)Were all crocodile relatives ambush predators? What other feeding strategies may have been used?

b)Some pseudosuchians looked a lot like theropod dinosaurs. How can we tell the difference?

c)Given the previous diversity of Pseudosuchia, why do you think only the Crocodilian group survived to the Cenozoic?

 

  1. Marine reptiles

Three iconic groups of marine reptiles were alive during the Mesozoic: Mosasaurs, Ichthyosaurs, and Plesiosaurs.

a)Did they all live at the same time? Which was the first to arise and which was the last?

b)Identify a modern analogue or relative for each of these groups.
