Here are three different recently acquired palaeocarcharodon teeth showing varying degrees of serrations. There is a bit of restoration done to the roots of one or two of them, but the blades and cusps seem to be in tact and the price was right. All three are from Morocco, and all three were found in the auction site...

Only if they've fossilized! :P

Nice idea. It's not like I'm far away from any deposits, but I still do sometimes buy or trade for some hard-to-get fossils. This is my most recent one. Euaspidoceras douvlilleifrom the Oxfordian at Villers in Normandie.

This monster mako (just under 3") was waiting for me when I got home today, stuffed between a bunch of bills.

This is my latest from a month or so ago. I purchased some Lance Formation matrix off the big auction site. Not to horribly expensive. First pic shows the chunks. They were bigger but I have (literally) broken them down into smaller pieces. I have about 2 quarts more of smaller bits in a container. I tried using vinegar on it but it didn't seem to be doing much. I have some muriatic acid but I am not currently inclined to use it on the matrix for fear of damaging the fossils. I can't find any hydrogen peroxide anywhere in town.

Nice looking matrix!

 

If the vinegar didn't do anything (minimal bubbles to be seen), then muriatic or other acids won't do much to the matrix either. If it bubbled a lot, but didn't appear to alter the rocks, that's typical for limestone--it takes repeated immersions to really get significant dissolution. I'd still be concerned for the fossils.

 

Have you tried using a freeze/thaw cycle? Try soaking the pieces of rock for a few days in small (pint or smaller) containers of water, then put in the freezer for a few days and let freeze solid. Take out the frozen chunks and melt in hot water, then put the unbroken rocks back in the containers with fresh water and back into the freezer. Repeat as needed. That simulates natural weathering fairly well. A cracked fossil might split, but they shouldn't dissolve!

 

Caveat: My experience is with micro-matrix; I haven't tried extracting bigger than a couple of cubic millimeters. ;) Good luck!

facepalm!!!

 

I knew I was forgetting something! Matter of fact, I have a baggie of Turonian age matrix (thanks Mike!) thats been freezing for a year so I do know about freeze/thaw but I forgot! Thanks!

I've been trying to budget a little better as of late, but this little guy and his not so complete friend were such a good deal I couldn't pass it up! Here's my latest score from a land far far away. The smaller, complete Eurypterid is about 3" long.

 

Balteurypterus tetragonophtalmus: Silurian. Podolski Region, Ukraine

A package from the Netherlands is always a good thing :)

Inside is one of my favourite shark species, Isurus escheri, showing varying degrees of protoserrations.

Cool topic!

I'm expecting something soon, which I will post as soon as I get it.

So far, I am very impressed with everything people received! :o

A denversaurus schlessmani tooth from Montana, Hell creek is my last purchase.

Great tooth! I saw it for sale some time ago, and I really wanted to get it, but the bids were just a bit too much...
