6[blank_start]Allotheria[blank_end]: [blank_start]Multituberculates[blank_end] (extinct) -- small rodent-like omnivores with broad multi-cusped teeth
[blank_start]Prototheria[blank_end]: [blank_start]Monotremes[blank_end] -- refers to cloaca with one opening for excretory and reproductive tracts
[blank_start]Metatheria[blank_end]: [blank_start]marsupials[blank_end] -- prolonged lactation, pouch
Eutheria: placentals -- prolonged gestation- AAllotheria
- BMultituberculates
- CPrototheria
- DMonotremes
- EMetatheria
- Fmarsupials
7Metatheria includes two sub-groups: the [blank_start]Ameridelphia[blank_end], or opossums, and the [blank_start]Australidelphia[blank_end], which include the Tasmanian devil, Tasmanian tiger, bandicoot, and others.
- AAmeridelphia
- BAustralidelphia
- CAustralidelphia
- DAmeridelphia
- EAllotheria
- FPrototheria

- HAllotheria
8Prototheria, or monotremes, include which animals?
- Aenchidnas
- Bopossums
- Ctasmanian tiger
- Dplatypus
- Ekoala

9The __________ is also known as the age of Mammals
- AMesozoic
- BCretaceous
- CJurrassic
- DPaleozoic
10The [blank_start]Mesozoic[blank_end], or the "true age of mammals," represents [blank_start]2/3[blank_end] of mammalian history. there are about [blank_start]300[blank_end] genera known from this period, although most were some form of [blank_start]mouse[blank_end]. Although this has historically been attributed to the fall of dinosaurs, recent evidence suggest that patterns of [blank_start]plant[blank_end] evolution had a greater influence on mammal diversity,
- AMesozoic
- BPaleozoic
- CCretaceous
- D2/3
- E1/2
- F1/3

11During which periods were the primary radiations in Mesozoic Mammals?
- AJurassic
- BCretaceous
- CTriassic
- DCenozoic
12The end-Cretaceous extinctions also affected mammals: lost [blank_start]marsupials[blank_end] and archaic type [blank_start]placentals[blank_end]. Mammals quickly recovered, but did not really start to diversify again until the [blank_start]Cenozoic[blank_end].
