Thought to be first lineage to diverge from lobe fins to tetrapods
Fish ancestor to all tetrapods, retaining a dorsal fin
Fish like ancestor, showing first digit development
Aquatic-terrestrial transitional fossil
First animals recognised as early tetrapods
Limbs with multiple digits

Lecture 2
Elongate, limbless amphibians
Body Segments of the above
Feeding on the Mother
Newts and Salamanders belong to this group
Gelatinous sperm cap used for external fertilisation
Retention of larval features
Salamander with large external gills
Name one of the 3 UK native newts
Frogs and Toads belong to this group
Calls often amplified by this feature
Yolk feeding
Name one of the 2 UK native Frogs
Name one of the 2 UK native Toads
Decline of a species despite good habitat and food supply

Lecture 3
Having a body temperature similar to surroundings
Warming up by laying in the sun
Process of breathing through the skin
Glands that create mucus to keep the skin moist (don't think too hard about this...)
Nitrogenous waste excreted by amphibians
(x) action by which the sticky tongue is ejected
Common example of disruptive colouration in frogs
Colours warning of toxicity
When the females are different in appearance to the males
Example of a spine used for defence in frogs

Lecture 4
Ancient amphibians that laid eggs on dry land, named for dental structure
Egg type laid by reptiles and birds
Development with no larval stage
Membranous sac surrounding the embryo
Membrane allowing for gas diffusion
Outpocket of gut used for waste storage
Where the yolk is stored
Holes behind the orbit in the skull
(x) have no holes behind the orbit
(x) have one hole behind the orbit
(x) have two holes behind the orbit
Stocky quadraped group now extinct, included Scutosurus
Group including turtles and tortoises

Scientific name for snakes
Swallowed by crocodiles for ballast

Lecture 5

Lecture 6
Dinosaurs and Pterosaurs
Crocodiles and other archosaurs
Bird Hipped Dinosaurs
Lizard Hipped Dinosaurs
Bipedal Carnivorous Dinosaurs (like Tyrannosaurus)
Long Necked Giant Dinosaurs (like Diplodicus)
Ability to retain body temperature, dependent on mass
Era of Dinosaur reign
Time of Dinosaur extinction
Meteor Impact site that may have caused the extinction
Large flood lavas that may have contributed to the extinction
