Low-cost approach polishing small carbonate rocks and fossils by hand
FranzBernhard posted a topic in Fossil Preparation
Some of you may have noticed my flat polished fossils and fossil rocks. A few of you have some of them in their hands, e.g. @ricardo, @taj, @Monica, @fifbrindacier, @marguy I lost access to the cutting, grinding and polishing facility recently. No great loss, but I still have some small specimens that I want to have polished. What to do? I tried a low-cost, low-effort approach, using things I already have. 1. Cutting: I tried to cut some small specimens with an angle grinder. Well, it worked, more or less. Not the best option, don´t to it. Better would be a tile sa- 19 replies

Archaeotherium upper jaw section
DawnOfADream posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everyone! Prior to the lockdown and money getting tight I won this at an auction, and it finally arrived today. What are your opinions and observations regarding its authenticity? I was also wondering about the white areas that appear to flow seamlessly with the specimen- is this also a binding product? It did say that it had restoration, and it’s clear that grey plaster/cement has been used, particularly at the front of the jaw where it appears to have previously broken. Thanks in advance! -
Since I asked it, this isn't a dumb question (is older up or down?)
SteveE posted a topic in Questions & Answers
As they said in school the only dumb question is the unasked one. So here goes... Instead of wasting field time fumbling around trying to figure this out, could someone please tell me how to read these sorts of section descriptions? Is the top of the printed list the top of the rock layer or the bottom? -
Hello all would this be a spino jaw section or a croc jaw section ? And the tooth has been put on the jaw.

I can't find any pictures of dino skull bone structure. Does anyone have any, or know where to find any cross sections, or pictures of skull fragments where you can see the internal structure? Preferably the forehead/top

Mosasaurus Jaw, double-checking authenticity ;)
FossilSniper posted a topic in Is It Real? How to Recognize Fossil Fabrications
I decided to (finally) spend some money and buy a mosasaur jaw section- my first jaw! I know that there are many fabricated mosasaur jaw sections out there, but I have ascertained for myself that this one is nothing to worry about. However, I still think that if there are indeed any problems with it, expert input would not hurt at all. Maybe I could even attempt extraction! (with the the proper methods, of course.) I really prefer fossils outside of their matrix- I am never content with 1/2 of a fossil while the rest remains entombed inside. Behold! Halisaurus (arambourgi?) Ja -

Hi all I found a large piece of an ammonite at Whitby, the whole thing would of been more than a foot across. Would be great if I could get what species of ammo it is. Thanks for looking.

Not sure if I included this query in an earlier post, but I don't think so. Is this just a convenient placement of individuals in a pile-up ? or are the parts associated ? I'll guess "pile-up", but the ribbed center section looks like the segmented portion of a crayfish ... of sorts. Maybe the thorax of a trilobite ? As always .... Thanks !

Hello all, I have a lot of unique dinosaur fossils from the Isle Of Wight (since I have a job on the island, and have been visiting there since I was of a young age) dinosaur remains are fairly abundant, however most of the time the larger more defined pieces are lost at sea or "beach rolled" (however I must admit you can get some really nice beach rolled pieces that show stunningly beautiful cell structures!). This jaw fragment if my memory serves me correctly was lying in a box in a locals garage (I believe the local passed away) the box was then given to a small museum on the island and t

More than 40 years ago I met a California desert rat who was nearing the end of his life. He took me to his storage shed and showed me an amazing collection of fossils and minerals he had found over the years. He offered me fantastic fossils at incredible prices, but I was a poor student living on macaroni and cheese. The one thing I bought was a doorstop that he said was some sort of petrified palm. It doesn't look anything like the petrified palm we find here in Texas, but I wondered if anyone had an idea of what this is:
