Acadian Orogeny

mountain building event – collision of two continental plates-Took place in the devonian period on east coast of north America

Acanthodian

first group of fish to evolve jaws- appear in silarian

Agnathan

any jawless fish

Ammonite & nautiloid

both are cephalopods. – nautiloids appear first, ammonite evolve from nautiloids in dovonian period- different shell structures separate the two- ammonites have more complex shells

Amniote

tetrapods that lay hard shell eggs and are classified by skull type- anapsid skull= no hole- only turtles living still – synapsid skull= mammal like reptiles-one hole- euryapsid= extinct- two openings on top of skull- diapsid skull- two openings lower behind eyes- lizards, crocidiles, birds, snakes

Anomalocaris

burgess  shale predator of cambrian sea survived at least till dovonian

Appalachian orogeny

uplift of mts during carboniferious period during forming of pangea

silarian jawed fish with armor – Dunkleosteus- was largest preditor of Cambrian period

Arthropleura

giant millipede type of Cambrian period

parts of trilobite

Axial lobe, cephalon(head), thorax(body)pygidium(tail),-

trilobites

are marine organisms- Paleozoic index fossils, disappear in Permian .

Bacteria

first life form’

Bivalve

clam

Blastoid

carboniferious period echinoderms- filter feeders

Brachiopods

Paleozoic invertebrate filter feeders – different than bivalve

Bryozoan

close relative of brachiopods-appear in orodvician

Lagerstatten

Crooksonia

first land plant in silarian with no leaves reproduced by spores

Crinoid

sea lillys -type of echinoderm in carboniferous

Cyclothem

sequence of sediment rocks in carboniferous- terrestrial rock on bottom to marine rock on top – formed from changes of sea levels

Enrolled

Epifauna

live on other organisms

Epifaunal tiering
