Regeants help- rocks and minerals?

Question

Does igneous or sedimntary contain fossils and i need to know more distinguishing charteristics to help me determine the type of rock i would have if i had one in front of me

Answer 1

Sedimentary rocks have fossils.  They are formed in layers.

Fossils would burn up during igneous rock formation since igneous rock comes from magma.

I see you mention Regent's so here is a good Regent's link:

Answer 2

Fossils are found in sedimentary rocks.

sedimentary characteristics: particles cemented together(such as conglomerate), contains shells (such as limestone), may show layers

igneous characteristics: intergrown crystals,(large visible crystals) vasicular gas pockets(it is very light and has a lot of holes), glassy volcanic rock (obsidian)
