1The two main clades of Osteichthyes are Actinopterygii and Elasmobranchii.
- AVerdadeiro
- BFalso
2Actinopterygii are [blank_start]ray-finned[blank_end] fishes, and Sarcopterygii are [blank_start]lobe-finned[blank_end] fishes.
- Aray-finned
- Blobe-finned
- Cray-finned
- Dlobe-finned
3Which of these are traits of Osteichthyes?
- Ateeth embedded in dermal margin mouth bones
- Bteeth connected to mouth bones by collagen
- Cdermal bones extend into roof of mouth to cover palate
- DGas containing structure used for buoyancy
- EOily liver used for buoyancy
4In Osteichthyes, asymmetrical fin skeleton is an ancestral trait.
- AVerdadeiro
- BFalso
5Early forms of Osteichthyes had [blank_start]thick[blank_end] scales, while modern Osteichthyes have [blank_start]thin[blank_end] scales
- Athick
- Bthin
- Cthick
- Dthin
6Actinopterygian scales: [blank_start]enamel[blank_end] ([blank_start]ganoine[blank_end])
Sarcopterygian scales: [blank_start]dentine-like layer[blank_end] ([blank_start]cosmine[blank_end])- Aenamel
- Bganoine
- Cdentine-like layer
- Dcosmine
7Compare the Skulls of the following:
[blank_start]basal Actinopterygian[blank_end]: complete dermal skull roof and no mobility of upper jaw
[blank_start]Sarcopterygian[blank_end]: complete dermal bone of skull
[blank_start]derived actinopterygian[blank_end]: reduced # dermal bones in skull, greater mobility marginal mouth bones of upper jaw, maxillae and premaxillae- Abasal Actinopterygian
- BSarcopterygian
- Cderived actinopterygian
8[blank_start]Actinopterygian[blank_end] brains develop by eversion, folding cerebral hemispheres [blank_start]outward[blank_end].
[blank_start]Sarcopterygian[blank_end] brains develop by cerebral hemispheres folding [blank_start]inward[blank_end] on themselves (as in Humans)- AActinopterygian
- BSarcopterygian
- Coutward
- Dinward
- ESarcopterygian
- FActinopterygian
- Ginward
- Houtward
9Early Sarcopterygii were [blank_start]cylindrical[blank_end] and [blank_start]20-70[blank_end] cm long. They had [blank_start]two[blank_end] dorsal fins and a distinct upper lobe on the [blank_start]heterocercal[blank_end] caudal fin. They were most diverse during the [blank_start]Paleozoic[blank_end].
- Acylindrical
- Bcompressiform
- C20-70
- D40-90
- E10-50
- Felongate
- Gtwo
- Hone
- Iheterocercal

10The three major lineages of Sarcopterygii are:
- AAcinistia
- BDipnoi
- CTetrapodomorpha
- DBodianus
- ECephalopholis
11Actinistia are also known as:
- Acoelacanths
- Blungfishes
- Cfour-footed fish
12What are the two derived characters of Actinistia?
- Adorsal fin that is supported by a plate of bone but lack an internal lob
- Bsymmetrical three-lobed tail with contral fleshy lob that ends in fringe of rays
- CLoss of tooth bearing dermal bones
- Dfin skeleton
13Coelacanths (Actinistia) have a vestigial lung.
- AVerdadeiro
- BFalso
14What are the derived characters of Dipnoi?
- ALoss of tooth bearing dermal bones
- BFusion of palatoquadrate to cranium
- Cteeth scattered over dermal bones
- DSymmetrical three-lobed tail with central flesy lob that ends in fringe of rays
15Actinistia is the largest genome among vertebrates.
- AVerdadeiro
- BFalso
16Dipnoans retained paired lungs.
- AVerdadeiro
- BFalso
17There is currently one extant species of Tetrapodomorpha fish.
- AVerdadeiro
- BFalso
18What are the derived characters of Tetrapodomorpha?
