Well, in recrystallization, the fossil would have been replaced with crystalline minerals. Look for the shiny stuff. Replacement is essentially just a mineral process. That is what you'd go with if any specific replacement method didn't fit. Premineralization makes internal molds of the organism specifically. It's like replacement on the inside. Hope that helps.Sunshine wrote:I'm not sure if this question's been answered already, and I'm sorry if it has, but i did a quick search and didn't find it... yeah
so, how the heck do i prepare for this event?
nah, jk, that wasn't my questionbut when given a sample, how can you tell apart the difference between permineralization, replacement, and recrystallization?

Re: Fossils B/C
There once was a group of teens
Who were lean mean science machines.
They liked to win medals,
when everything settles
and their favorite color was green.

Re: Fossils B/C
Would fossilization occur better in a high mountainous area or in a desert? Also, would big bones or small bones fossil better....see, im thinking big bones cause obviously they take longer to decompose, but the smaller bone could get covered up faster.

Wikipedia ftw.sr243 wrote:any good website to find common names for species, cuz different places give different names. Others don't really have a common name.
Seriously...
Other than that, use search engines to your advantage.

Re: Fossils B/C
Keep in mind that most of the fossils you need to go to Genus, not species. So species tend to get their own common names, while the genus could show up as multiple things.sr243 wrote:any good website to find common names for species, cuz different places give different names.

Re: Fossils B/C
Yeah, also, you probably often can't find that. The vast majority of individual fossil species don't have their own common name. For instance there is not a common name for most individual species of brachiopods.gneissisnice wrote:Keep in mind that most of the fossils you need to go to Genus, not species.

Even many of the less specific taxon on the actual list have no common names. Cryptolithus is Cryptolithus, Tyrannosaurus is Tyrannosaurus, etc.

Re: Fossils B/C
heres a question for all you fossil gods.
what is the easiest method of identifying the mode of preservation? those questions cost me a medal at states

Re: Fossils B/C
Yes, i got first in my division (A div, which is lower, compared to AA) but 6th overall at state...i was also in a pickle cause of preservation. Seriously, how do you tell if its replacement/petrification (permineralization)/recrystallization? Dont tell us wat it is, dont mean to be rude, just seems like thats wat happens everytime, we just want a way to recognize them...quizbowl13 wrote:heres a question for all you fossil gods.

Re: Fossils B/C
Haha thanks...and wat about echinoderms messed u up? I really like echinoderms, really easy to identify and and stuff..also, i know a lot about them cause i did a report on it for Bio in school this yearquizbowl13 wrote:completely agreed.lllazar wrote:Yes, i got first in my division (A div, which is lower, compared to AA) but 6th overall at state...i was also in a pickle cause of preservation.
