Trip report: The Fabulous Fossils of Pas de Calais!
FossilLerp2 posted a topic in Fossil Hunting Trips
Hello everyone, and welcome back to another trip report! Last week, me and my family went to France once again, but this time to northern France, near Cap Blanc Nez. Cap Blanc Nez is a well-known fossil-hunting site for its ammonites and other fossils. It is located quite near the coast of England, and if the weather's clear you can see the cliffs of Dover very clearly. Day 1: it's a start The first fossil trip was rather disappointing. We walked down the stairway to the beach and headed directly to Grand Blanc Nez, the main landmark in the area. We started search- 9 replies

Life reconstruction of the Ammonoid Koenenites
Bringing Fossils to Life posted a topic in Paleo Re-creations
Here's the reconstruction of Koenenites I promised. Koenenites was a Devonian ammonoid with a very compressed shell and sharp keel. It was designed for fast swimming and thanks to the shape of its suture, it could accelerate very quickly compared to the ammonoids around it without its cameral fluid sloshing around and shifting its center of gravity. Because of its evolute shell, it likely had a large hyponome, which goes with the shape of its shell. After looking at some pictures of Koenenites fossils from Michigan that may have preserved the Supercephalic Attachment Area, I arrived at the pro -

I found a few days ago this fragment of ammonite, (Cretaceous). I was wondering if any of you might recognize her.

I’m not sure what this is. This little croissant shaped guy struck me as interesting as I was hunting through a pile of limestone in our new construction neighborhood in northern Bexar County, Texas. It’s in northern San Antonio. I thought it might be a shell of some sort. It’s about 4.5 to 5 inches wide and about 1.5 inches in depth. It has striations here and there and a shape that looks like a nautilus, but may just be an interesting concrete on or piece of limestone. Anyone got any ideas or answers? The ‘center’ of the ‘croissant’ has a grayish area that’s really differen

One of my favourite fossils in my collection: a Cleoniceras sp. ammonite
gond posted a topic in Member Collections
This is one of my favourite fossils of my collection. Hope you like it too! ------------------------------------------------------------------------------- Species: Cleoniceras sp. Size: 6,6 cm x 5,3 cm x 1,9 cm Age: 145,5 mya (Lower Cretaceous) Origin: Tulear, Madagascar About the fossil: the beautiful red color of the shell and the more "white" one near the center of the specimen are a product of opalization (more specifically, the type of opal that formed in this specimen is red opal). Edit: It's not opal, it's aragonite.- 12 replies

Didymoceras cheyennense?
Mochaccino posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, Does this association of Didymoceras cheyennense and Baculites compressus seem legitimate? Any restoration/reconstruction going on, or composite of multiple individuals, especially on the Didymoceras? Dimensions are 22cm x 14cm x 14cm, and listed as of Lower Cretaceous age and from the Pierre Shale of South Dakota. Also, if you had to pick one heteromorph ammonite specimen, would you personally purchase this for your collection (i.e. is it a good example of Didymoceras cheyennense)? I realize this is just a part of the inner whorls. Complete Didymoceras in gene -
Has anyone got any advice on drawing ammonites accurately? It is often the ribs which identify an ammonite, so they are very important to get right and while I my observational skills are fairly good, I find it hard to believe people like Ernst Haeckle relied purely on observation. I don't strive for Haeckle's realism as I draw in a more sketchy manner, but I do strive for accuracy all the same. Is there a sort of formula to plot ammonite ribs? Thanks!

Fossils Solnhofen, Germany. Need identification if possible
AnyArthropod posted a topic in Fossil ID
Hello everyone, I went to a fossil deposit in Solnhofen, Germany a few years ago. I never got all of my finds IDed however. I would appreciate your help if you have time. Thanks for your intrest, -AnyArthropod -
On our last fieldtrip to France this weekend we found a chalk-boulder with a quite large ammonite in it. The chalk was realy hard, but I was able to reduce it in size to take it back home. At the start of the prep with chislle and hammer I got a lucky split where the boulder opened to reveal most of the ammonite. The airscribe then did a quick job to remove the last bits. Sadly the center of the ammonite wasn't preserved, I tried to sculpt the center as well as I could and coloured it to match the fossil. As for the determination we had a little doubt between Cunningt

Hi everyone, I went fossil hunting on the Yorkshire Coast a few days ago and picked up plenty of Dactylioceras ammos but not much else. Among them are these two which both cracked after an exploratory 'tap' with the hammer. I have never glued broken ammonites together for prep before but have seen it spoken about a lot. I have a few questions about how to approach this. Firstly, do you think these specimens are viable? The other issue is that I only have a Dremel to prep with so even if I glue them back together there will be an awful lot of matrix to remove..

Hey y'all, here's an ammonite I found in what I'm fairly sure is a small, unmapped Eagle Ford outcrop. I'm hoping to use it as an index fossil, as the target species that I'm hoping this outcrop will produce occurs in the late cenomanian/early turonian Bouldin Flags member of the Eagle Ford formation. I find that the written descriptions that I've read about the bouldin flags geology are inadequate for my understanding, as it seems colors, shades, and degree of textures are up to the interpretation of the reader. Maybe I'm just overthinking that though. Hopefully this ammo helps.

Hello, I had a question about the coloration of the beautiful South Dakota ammonites from the Fox Hills formation/Pierre Shale. Namely, many Hoploscaphites/Discoscaphites ammonites have a milky white nacre of the shell, whereas others seem to have a vibrant red/brown sheen. For example here are two photos of Hoploscaphites nicoletti I found demonstrating the two types of colorations: I was wondering what causes the difference in this coloration, and whether one is more rare/valuable than the other? I want a nice South Dakota ammonite for my collection

I purchased several of these inexpensively as giveaways for children. The dealer was somewhat clueless as to the origin. I don't normally buy fossils but I assume they are commonly offered for sale since they were so cheap. Does anyone recognize where these are from and any other bits of information? They seem relatively heavy, almost like hematite replacement. Picture of a representative example:

Fossils Collection, Are they real & ID
Trilobit posted a topic in Is It Real? How to Recognize Fossil Fabrications
Sorry for a lot of posts recently Cleaning house and have found some in storage Here are all the ones that were found. Any that can be identified + age, and are any fakes? I'm suspicious of the black trilobite I can retake photos if needed, any information would help -
Hi all - I am trying to find out the type of ammonite I have here and any other helpful information like age and where it's from. ammonitepics.zip

Hi all. I found this piece today in Withernsea, Yorkshire. I have a Dremel and I've made a start on prepping it but I'm scared of damaging hidden ammonites. Any suggestions? Also, what type of ammonites are they? Thanks for any advice.

Alright folks, just sit right back and you'll hear a tale, a tale of our fateful trip... but if your in a TLDR mood.... Fossils get real heavy, real fast, and we found a lot. I had a rare full weekend off work, so my son and I went back to hunt the lake Texoma shoreline for a 2 day exploration. We started off in the same beach we found last time (that I dubbed "Echinoid Beach"), but construction had changed everything and made it much harder to hunt. The worst part is that last time we left a small pile when moving everything back to the truck. I knew where it was, but when we a

Coolest fossil I've seen as part of a building material
Jared C posted a topic in General Fossil Discussion
Today I noticed a decorative ammonite built into a limestone wall of a bathroom at champion park here in round rock - while cool on its own, it's when I walked up to it to look closer that I saw a neat little detail. On the surface of the ammonite, there's a little blade of a shark tooth - not so big that it's its own feature, but I find it unlikely that a collector would've yielded such a nifty little dual fossil if they knew it would go on a public bathroom wall. So, I think this little tooth probably wasn't noticed at first. ...this little observation gave me copious- 3 replies
