Hello! I won an auction online to buy this ammonite someone found in a storage unit, they thought it was a snail! Any ideas on identification? The storage unit is in the USA but that doesn’t help with where it came from..I’m sorry but hopefully you understand the lack of information available given the background of how I acquired it. Madagascar is my first guess but I am ignorant on this topic and only know what I know! I don’t have it in my possession just yet.

I was given this ammonite for Christmas by a co-worker that was moving out of state. He had no info on it unfortunately. 12.5cm at the widest by 3cm at the thickest. No ornamentation along the edge, but it does have some iridescence across both sides. Tried to get some of it to show in the pics & managed some. Color is an almost pearl white in hand. Any idea's?

Hi all, I had a little trip to the Jurassic coast this weekend gone. During that time I found a lovely bit of iridescent ammonite poking out of a rock that had slipped down. There are a number of other ammonites in the rock too. I was wondering if anyone had advice/criticisms of my prep plan. I've not worked with iridescent ammonites before but understand them to be quite flaky. Step 1 Soak to reduce salt water content. I've given it a good soak in tap water last night. Not sure if more is required but on previous fossils from the coast I've never had any issues doing it that way. Step 2 10% paraloid solution on the exposed iridescent section. Step 3 Use a prepping pick to carefully remove the matrix and as I go, add further paraloid to freshly exposed ammonite. I want to avoid using my Dremel as I think the vibration could cause damage potentially. Do this sound ok to you all?

I've been seeing picture of small Iredescent purple pyritic ammonites found the in UK, I've looked unsuccessfully for a location online. Can anyone help? Thinking south space, maybe Somerset as the colouration is similar to those found in Watchet. Thanks in advance!

Is this Iridescent ammonite real?
GallinaPinta posted a topic in Is It Real? How to Recognize Fossil Fabrications
So this ammonite was listed for less than 4 dollars but I think it's too pretty. The seller didn't post any other photos unfortunately. They are supposedly from morocco but the seller is from china.

Silver Iridescent Ammonite Fossils Mahajanga Province, Madagascar TIME PERIOD: Middle Cretaceous (110 million years ago) Data: Ammonoids are an extinct group of marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs are more closely related to living coleoids (i.e., octopuses, squid, and cuttlefish) than they are to shelled nautiloids such as the living Nautilus species. The earliest ammonites appear during the Devonian, and the last species died out during the Cretaceous–Paleogene extinction event. Ammonites are excellent index fossils, and it is often possible to link the rock layer in which a particular species or genus is found to specific geologic time periods. Their fossil shells usually take the form of planispirals, although there were some helically spiraled and nonspiraled forms (known as heteromorphs). The name "ammonite", from which the scientific term is derived, was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled rams' horns. Pliny the Elder (d. 79 AD near Pompeii) called fossils of these animals ammonis cornua ("horns of Ammon") because the Egyptian god Ammon (Amun) was typically depicted wearing ram's horns. Often the name of an ammonite genus ends in -ceras, which is Greek for "horn". Kingdom: Animalia Phylum: Mollusca Class: Cephalopoda Order: Ammonitida -

This was the first fossil in my collection, yet the age, formation, species, and place of origin are all unknown to me. I assume it was from Madagascar. Bought for me as a present. -
