Fossils B/C

[coprolite_dipstick]

Can we have each question only have a set of questions applying to a single specimen/picture, or on a single topic? I know that's how the actual event works, but with so many questions and answers, this thread is really messy.

e. g.

//Specimen picture\\

1.What genus was it?
2.When did it live?
3.etc.

Sure

Someone should go. No one has posted in a long time

1) What are stromatolites and who made them?
2) What kind of fossilization is stromatolites categorized as ?
3) Why are they significant?

There...

1) Microbes acting as a colonial species, much like sponges, bryozoans, or corals, but stromatolites are not animals.
2) Since there aren't any actual or fossilized remains of the organism, wouldn't it be trace fossil?
3) As they are found as early as the Archean Eon, they are the first evidence of life in the form of fossils.

I will say correct, but from sources I have found that they are made by algae[newer] and cyanobacteria[older] (you should include more information on a real test). Also for 2 is a real easy one because it's under the trace fossil section :S

As far as I know, they're made of cyanobacteria, which may be where the "algae" part comes from; if I remember correctly, they are sometimes called blue-green algae.

Yeah, I've heard both algae and cyanobacteria used for stromatolites.

As nationals are fast approaching, I will try to increase the difficulty of questions. (Click to Show Hidden Text)

1. Identify all main taxonomic ranks
2. Common name
3. What periods did it live in?
4. How is this different from the majority of species in this class?
5. What continent is it usually found on?

[Unome]

I know some of them (Click to Show Hidden Text)

1. Mollusca, Bivalvia, Gryphaeaidae (I don't remember the Order, just the Phylum, Class, and Family)
2. Devil's Toenail
3. Paleogene to Quaternary?
4. They were more common in the Mesozoic
5. No idea
