    Carbo and Pyrit, not sure if Pyrit would be acceptabke?
    Pyrite could work because it's a form of replacement in an anoxic environment which preserved graptolites are found in.

    I Remember in the textbook that it says graptolites can be preserved by carbonisation. We were never taught what it's exact composition was.


    Yeah I can't remember that one.

    With the two brachiopods did you put the mode of life for both was benthonic, epifaunal sessile?
    I put the pedicle one as epifaunal, and the second as infaunal. Pretty sure i got the infaunal one wrong

    It's always carbonisation
    they cant be preserved below the CCD if it's by carbonisation.... there's literally no carbon in them which is kinda necessary for carbonisation lol

    Graptolites is the most commonly found preserved due to carbonisation, i'm sure

    yea i got replacement and pyritisation cause they're preserved below CCD so no carbon
    That's calcite compensation depth.

    (Original post by savingwonderland)
    Yep but for the first i put attached by the pedicle and the second i said free lying with spines to spread weight
    Yeah I put the same but spines acted as anchors.

    Nooooo noo its 10000% carbonate compensation depth google it, its ingrained in my brain from how many times my teacher covered it last year and this year. Anyways im logging off my brain is 110% done with geology forever, good luck with results folks you sound like you did better than the vast majority of my class so you've got little to worry about

    Yeah calcite is a carbonate but schleroprotein isn't (got full name wrong). Good luck with yours as well.

    The 4 marker on adv of biostrata to litho for fossilerferous linestone, what did you put down

    Pretty sure that was 2 marks. I put that litho could correlate beds of different ages if two different beds appear the same in different areas. Then put about the large amount of fossils which could be used to correlate beds. Think the second part I put was mediocre, probably wanted this fully: large amount of fossils will have varying ranges and if a bed contains several fossil types then can be correlates to another with all those (since it didn't state any zone fossils).

    I talked about diopachronus beds causing problems :/

    Yeah that would be another good one. The question didn't state rock type, only that a sequence is fossiliferous so could be any rocks with lots of fossils.

    So what do you think the GBs will be? Last year it was 70/100 for an A

    I feel like it will be around 73 for an A. Mostly decent questions, 6 and 8 were the nasty ones. I think that the unit 4 will be quite low.

    I hope mate :/
    What was the function of the tabula

    The question on trace fossil, and it asked about 2 sedimentary additional observations to infer environemental something like
    Were i on the right track talking about grain size and cross cutting relationship?

    They strengthen the corallite, don't remember a question their function. Only that one asking what species had them.

    Grain yes since it shows energy levels. Don't think so for cross cutting since that tends to be for stuff like igneous intrusions and faults which aren't due to deposition.

    what did people shade and circle on the question that asked for one interambulacral plate, i shaded one whole strip then changed my mind and did a singular plate on one of the strips?
