Hi All, Over a year ago I found this in situ NSR - Ozan formation Late Cretaceous; Gulfian Series. It's the only one I've found like this in both size and fossilization. I'm terrible with ammonite identifications and would love to put a name to this little specimen and an opinion on if this might be a heteromorphic ammonite? Might it be a Scaphites sp? Thanks!

These heteromorph ammonites were found in the middle East in a senonian outcrop. In a limestone but the fossils are made of flint and removed by acid. the pieces are 3-4 centimetres long and are three different individuals. Can you please help me ID them?

I was considering buying this heteromorph ammonite from an online dealer and was just wondering if it looks authentic. Any advice would be much appreciated!

From the album: Fauna and Flora of the Austin Group in Texas
This specimen is the largest of its genus in my collection, and the largest known to me in any collection. It measures about 7 cm in height, and 4.3 cm in diameter. It retains its tubercles in the most mature whorl sections that are preserved well enough to tell. The specimen is quite crushed. -

Almost 2 weeks ago I went with a small group from the rockhound club up to the Vancouver Island Paleontology Museum and the Courtenay & District Museum to see their fossils. Weather was too crummy to do an actual collecting field trip at any place! I guess it's OK to post pics here. I won't post anybody's face. The lighting and some of the display cases themselves presented problems for photography at both places, besides which it was kind of a whirlwind tour, so these shots are the best I could do. I'd say the poor lighting was the worst thing about both places, but we're dealing with small museums with small budgets here, so I figure that can be excused. First, Graham Beard gave us an informative tour of the VIPS in Qualicum Beach. It is a one-room fossil display, aimed primarily at educating the public, and Graham's tour was likewise, which suited us fine as most of the rockhounds know next to nothing about fossils. I think we all got more out of it than we would have if we'd been left to view it all on our own. He not only explained what was interesting about many of the pieces but also recounted the stories around how some of them were collected or acquired. He started at the 'types of preservation' showcase, which featured a piece from the Appian Way site up toward Campbell River which contains Eocene plants. It had been sliced and peeled to reveal fine cross-section detail of the plants. Several new species have been described from here. If you look closely at the slab leaning at an angle on the stand you can see a sheet partly peeled off: Heteromorphic ammonites from Hornby Island and V.I.: The big dark one in front, I have a piece of the same taxon from Mt Tzuhalem. Mine is missing the crook part but looks identical to the straight part. I thought it was from my mountain until Graham told me it was from up along the Inland Island Hwy near Courtenay. (Nothing to collect there now, as that was when the hwy was being built or widened). It didn't have a label and Graham couldn't remember so I'm still not sure what it's called!

Ralph @Nimravis generously gave me these Ammonites. I think he bought them at a garage sale. There was no data with them. I have zero experience with ammonites. I am hoping someone will be able to put a genus name on one or more of them or even venture a guess as to from where they may have come and what time period. Does that matrix / assemblage look familiar to anyone? One appears to be a heteromorph. I think I see Inoceramus in there. Maybe Cretaceous? Texas? They are all the same color (differences in color between the pieces in the photos is due to different lighting). Scale is in cm/mm.

Heteromorph ammonites- why the weird shapes? I am at a loss...
-
Creek was a little flooded today made it harder to navigate, started the day with 2 dead drill battery's that I had charged the night before so I decided to move father up to look at some different exposures, started by picking up some matrix for micro's from the bottom of the pecan gap, more on that later, and then some Del Rio clay for the same, (if someone has suggestions for how to wash this faster that would be great) spent the next 2 hours picking up heteromorph mariellas.

I went hunting in the rain yesterday. It wasn’t one of my most successful hunts, but I still managed to find some cool stuff. I found this in The Grayson Formation, Cretaceous in the Denton, TX area. I had never hunted that area of the Grayson before and it was different as every area of the Grayson seems to be. I found this section of a heteromorph. I don’t believe it is a Mariella. I am wondering if it could be a section of Turrilites. I believe it only has 2 rows of tubercles. Any thoughts? Side view Top down view Edge view

Help restoring Heteromorph Ammonite from Morocco please.
JavierMS posted a topic in Fossil Preparation
Greetings, I recently bought an Heteromorph Ammonite fossil from Morocco (my first moroccan ammonite) and I decided to clean it with a little bit of water the same way I did with previous fossils. Big mistake... since I was shocked to see how the red ammonite turned brown and some parts disappeared (those put together with some sort of brown putty) when I put the ammonite under the water... After speaking with some fossil collectors I found out that many Heteromorph Ammonites from Morocco are indeed broken and put together, and they are sometimes "created" using the parts of different ammonites... You can see the ammonite before (the red one) and after (the brown one) and what I would like to know now is how to restore it please. What is the brown putty they used to put all the pieces together and how do they obtain that red colour? Is it totally necessary to use the same procedure? I've been creating and painting clay sculptures for years and I wonder now if using some clay and acrylic paintings would work... Thank you very much.

From the album: james herrmann
In this right side view of the sculpture I would like to show the green marble base. I chose this mottled green marble as a continuation of the kelp forest theme. I envision this ammonite pulling its way along the waving fronts of a kelp forest as it forages for small crustaceans. Kelp forests are contrasts of warm, bright beams of light and deep shadow. The marble is mottled in various shades of green much like looking down onto the kelp forest's waving fronds.- 2 comments

In this view I again wanted to show the cantilevered structure of the sculpture and the subtle color differences in the patination of the shell vs the body of the ammonite. -
From the album: james herrmann
In this front left view I wanted to highlight the waving of the kelp. The challenge was to strongly support the heteromorph while still making the sculpture feel like there was movement and a lightness to the work. -
From the album: james herrmann
This left side view of the sculpture shows the attachment of the ammonite to the kelp, actually there is a lot of bronze in the mass of tentacles. From the base to the top of the sculpture is approximately 40 inches. -
From the album: james herrmann
I like the complex repeating nature of the spines in this view of the sculpture. I am supporting the mass of the bronze ammonite with the bronze kelp leaves welded into a trellis-like pattern to carry the weight down to the base. -

Heteromorph is my most recent sculpture with a paleontological theme. This is the rear view of the sculpture showing the shell spines. -
Somewhere, I posted about the receipt of this ammonite from @RJB‘s cast off pile. I finished up the prep yesterday. Unfortunately, I don’t know these ammonites well enough to give it a good ID. I know there’s someone here who does though. I gave up on the back ammonite as its quality wasn’t worth my time.

Well, after over 6 months of lurking around on this forum, observing all the fun everyone else is having, I guess it is about time that I join. Greetings! I live in North Texas and I began hunting fossils about 9 years ago. But not all that time was spent in true dedication to this wonderful science. It is only till November of last year that the fossil bug in me has been reawakened after about 6-7 years of largely steady hibernation. I have spent the past few months catching up to what I had forgotten, and I am learning about many new things that I never knew about before. For now, I mainly hunt in the Coniacian stage of the Austin Chalk formation, which is in the Middle Cretaceous, since I live on top of it and it is the stage of that formation in which I got my start. I do hope to be able to spread out my hunting range over time though. But for now I am quite content where I am. I hope to be able to bring to light the geology, fauna and specifically the lesser known ammonites of the Coniacian stage of the Austin Chalk that I just so happened to have found my self in. In fact, my profile picture and my cover photo are of a nearly complete specimen of an unusual species of ammonite from the Coniacian stage of the Austin Chalk. I found it accidentally when I picked up the top piece of a rock with a large inoceramid on it that had separated from the base of the rock after sitting outside for over 6 winters in my back yard. It was kindly identified by Ron Moran as the rare species Phlycticrioceras trinodosum, a heteromorphic ammonite. It is definitely one of my favorite finds! I am truly thankful for the fortune of being able to live in an area of such paleontological richness, not just in the Austin Chalk formation, but in Texas as a whole! I hope to be able to contribute to this forum and to learn from the many people on here who are far more wise and knowledgable than me.

Inside the heteromorph ammonite Scaphites
Douvilleiceras posted a topic in General Fossil Discussion
Hello All, Recently, I've acquired a sliced half of the Cretaceous heteromorph ammonite Scaphites. While rarely sliced, I managed to find one buried in a pile of similarly sliced Madagascar ammonites, and purchased it. Here are the photos: 1. A view of the whole ammonite. Here, we can see the phragmocone as well as the sediment-filled living chamber. 2. A closeup of the phragmocone, showing the beautiful septa. The minerals are very pure in this example, making some chambers appear as if they are filled with a tinted glass. 3. The point of no return: the outer whorl splits off from its counterpart, creating the unique shape which Scaphites and its relatives are known for.
