paleontology Flashcards
what is the age of trilobites?
Cambrian
this is the main group of paleozoic anthropods used in the zonation of the Cambrian period
trilobites
in silurian and ordovician mudstones and were used to indicate rapid evol and have allowed a high resolution biostratigraphy to develop the silurian and ordovician system
graptolites
regional correlation purposes only in silurian rocks due to sessile lifestyle
age: silurian
brachiopods
age: mesozoic-cretaceous
main zone fossils for mesozoic and became extinct at the end of the cretaceous
ammonoids
aage devonian-carboniferous
early form of ammonoids that have been used in correlation of devonian and carboniferous rocks
goniatites
abundant in cenozoic rocks
age cenozoic
gastropods
age cretaceous
fossil of sea urchins that have been useful in correlation of regional and worldwide correlation in parts of cretaceous
echinoderms
age paleozoic
fossils of sea lilies that were abundant in some paleozoic limestones
crinoids
age devonian mississippian
contained in extensive outcrops of shallow marine limestones in devonian and mississipian and have been used as zone fossils within these strata
corals
age cambrian devonian
fossils in strata as old as the cambrian forams that have tests did not become established until devonian
calcareous forams became more abundant through the phanerozoic and abundant in mesozoic and cenozoic
foraminefera or forams
age paleozoic
important in dating deep marine deposits because their skeletons survive as siliceous ooze below CCD stratigraphic range is also greater tean forams making them important in paleozoic strata
radiolaria
age mesozoic cenozoic
spherical calcareous cyst of marine algae and the main constituent of some fine grained limestones such as chalk of the upper cretaceous in northwest europe
coccolithophores
age ordovician
zonation is applied locally in both marine and non marine envi
ostracods
age proterozoic phanerozoic
microscopic spiny structures made of organic material used in proterozoic and paleozoic rocks
acritarchs
age phanerozoic
primitive organisms found from phanerozoic through to the presesnt day and zonation are important
dinoflagellates
age jurassic
siliceous single celled algae
diatoms
age cambrian triassic
ancient worm like animals composed of calcium phosphate
