Triceratops Posted October 16, 2014 Share Posted October 16, 2014 I found this piece of concrete near a demolition site a few years ago. It is a imprint of a pohutukawa leaf. Does anyone else have a modern 'fossil' they can share? -Lyall Link to comment Share on other sites More sharing options...

Ash Posted October 18, 2014 Share Posted October 18, 2014 That's really cool, triceratops! Ha, Missourian - I don't even know what those are! Definitively primitive!

jpevahouse Posted October 23, 2014 Share Posted October 23, 2014 (edited) That's a good question. I suspect metal artifacts buried in mud under tons of pressure for a few million years will eventually end up embedded in solid rock just like other fossils. Those look great!

Missourian Posted October 23, 2014 Share Posted October 23, 2014 I'd think so. Even if they corrode away, there would still be a mold in the matrix, and perhaps an oxide cast or even a steinkern in some cases. Context is critical. Link to comment Share on other sites More sharing options...
Triceratops Posted October 24, 2014 Author Share Posted October 24, 2014 Thanks. I wonder what future people will think of all our strange artifacts? -Lyall Link to comment Share on other sites More sharing options...
Wrangellian Posted October 28, 2014 Share Posted October 28, 2014 ... Ha, Missourian - I don't even know what those are! Definitively primitive! You must be pretty young, grasshopper! I'm 38 but there are times when I feel a lot older... Link to comment Share on other sites More sharing options...

Ludwigia Posted November 6, 2014 Share Posted November 6, 2014 Beech leaves (Fagus) found in a modern sinter terrace in the hills not far from home. The slope is just full of them together with lots of moss, etc. You can practically watch the fossilizing process in progress at this spot. Greetings from the Lake of Constance.

painshill Posted November 6, 2014 Share Posted November 6, 2014 (edited) Those look great! I wonder if metal things can fossilise? If we consider fossilisation as a mineral replacement process then the answer is yes. I've mentioned previously that there are places in the UK where there are salt-marsh environments that were used for bombing practice during WWII and it's not uncommon to find pieces of military ordnance (shrapnel and ammunition rounds) that have seen such replacement. They're usually found as sideritic nodules and can form in tens of years. There are also instances of more ancient partly metallic "fossil meteorites" found in dried-up lake beds in NW Africa and meteorites that have converted to iron shale in Australia and China. I also remember seeing a "fossilized" (ie mineral-replaced) wooden fence post that was no more than a couple of hundred years old. I think it may have been in the Melbourne Museum in Australia. You may remember these as well: http://www.thefossilforum.com/index.php?/topic/45738-petrified-dinosuar-full-body-preservation/ Edited November 7, 2014 by painshill Roger I keep six honest serving-men (they taught me all I knew);Their names are What and Why and When and How and Where and Who [Rudyard Kipling] Link to comment Share on other sites More sharing options...
