Continuing with the teaser title... What does it mean when you find a partial ammonite outer whorl of these dimensions? 10 cm X 15 cm. 1 - I'm gonna need a bigger vehicle 2 - Just a lucky fluke 3 - Get back out there and find its siblings 4 - It's a fake plaster cast with which someone spiked the site 5 - These aren't the Ammonites you're looking for, move along 6 - Pay no attention to the peanut butter M&,M's nor the Reese's cups, I'm still celebrating!!! So I'm 3 fossil hunting trips behind and I had a 48 hour binge including two of said trips and one Astrophotography session with Orion Pleiades and Jupiter from 9 pm to 12 am; interject a 2 hour nap, then a 3 hr session with the Milky Way from 230 am to 5 am when the crescent moon rose and ended the session. Then another 2 hr nap when my wife texted me awake from home while I was snoozing comfortably in the back of my Honda Element in The Last Chance Desert. Then jump back into the fossil hunting saddle, a museum visit, plus Jurassic National Monument and more. Oh and not to forget that famous Clawson, UT UFO Landing Site. I gotta lotta catching up to do. This partial is an adult Prionocyclus macombi sp., the gracile form . I will attempt to estimate the possible diameter ASAP. Steve

Hi all, I'm a total newby but have always been fascinated by fossils, geodes (especially Brazil/Uruguay amethyst) and Roman / Greek / Byzantine coins. I have a nice collection, and have recently purchased some Whitby, Yorkshire ammonite nodules. I'm using the freeze thaw method to open them, as I tried cracking two and both are damaged. However, one nodule is brown, not the black shale as the others, and really soft - I can remove the concrete with my fingernails. My question is how a 180 million year old fossil can be so well preserved in soft mudstone, and is this something others have seen? Was it free of concretion and then collected a new one? It's in very good, nearly complete condition. I'll send a pic shortly.

The Ammonites of Madagascar are globally renowned, with numerous well-preserved genera and species. However, I've never seen one of these specimens in an unpolished state, as most are heavily polished. Does anyone have a photo of these fossils in a more "natural" condition?

Ammonite - real or fake?
CuentoDeHadas posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello again helpful people! I am back requesting any information people can tell me about this ammonite I bought? I didn't previously have any suspicions about it being fake (and don't really understand how the pattern in the stone would be faked). However, I have since bought a trilobite from the same source (that you may have seen in my previous post) that did turn out to be fake and that I will be returning. I still have the option to return this one as well if it is fake so appreciate any feedback! -
I found my 2nd ever ammonite in what I’m calling the Grayson formation, based on Mancos app showing solid Grayson, though it’s fairly close to the paw paw. Tarrant County, TX. I’m not well educated on Main Street though, so maybe that fits in here somewhere? Either way, I’ve been to this spot numerous times, lots of cymatoceras nautiloids and I got my biggest turrilites from this spot too. I was thrilled to find a 2 pound, 5.5 inch ammonite. I am GUESSING it might be mortoniceras parinflatum? If anyone can confirm or correct, much appreciated! I used the Kennedy paper on Grayson/Mainstreet cephalopods. I can’t wait to clean it up with air abrasive/air scribe to see what the center looks like.
