"Stone" for Macro Mondays. Many thanks for your visit, comments and favs, they are all much appreciated :) HMM
the shell of a marine animal that lived during the period of earth history known as Jurassic & Cretaceous - it became extinct at the end of the Cretaceous Period - roughly the same time as the dinosaurs disappeared.
This ammonite shell from my collection dates back to the time that I was studying some geology at University and shows off quite well the wavy nature of the complex patterns within the fossilised structure of this now extinct sea creature.
As the ammonite grew, more chambers were formed with a wavy septum or partition made, dividing the old from the new ones, much like the septum dividing our two nostrils from each other.
The whole fossil is approximately 3 inches at its longest breadth so fits the requirements for the task.
Cette pièce d'Ammonite fossilisée incrustée de Citrine présente une spirale presque parfaite. C'est autant un art naturel qu'un phénomène géométrique et arithmétique à la fois. #Macro #MacroMondays #Spiral
Ammonite Falls can be found outside of the city of Nanaimo on Vancouver Island, British Columbia, Canada.
Sorry it's not pin sharp, but they let me take this in the shop, and it's just such a pretty piece!!
35 A spiral or swirl
The pearl coating on the shell off this fossil ammonite still refracts a rainbow of colors despite being many millions of years old. In the Milwaukee Public Museum collection.
Have I mentioned that I love spirals? :-) One of the most fascinating patterns in nature.
Detail of a decoration item I got as a gift. All other gifts I have already eaten !
An example of an Ammonite iridescent - from the Cretaceous period that spans 79 million years from the end of the Jurassic Period. Climate was relatively warm, resulting in high sea levels which created lots of shallow inland seas populated with many examples of ammonites.
El fósil amonites proviene de un molusco cefalópodo, los ammonoideos. ... Los ammonites son animales marinos que prosperaron en las Eras Paleozoicas y Mesozoicas, parientes extintos de los calamares, pulpos, sepias y nautilos que conocemos en nuestros días.
I have too many collections! This is part of a small collection that I have of fossils, rocks and minerals. This beautiful ammonite was bought when I was living in Kenya many years ago!
This is a four photo shot of a fossilized ammonite that has been stitched together. A fairly common fossil, this ammonite was cut in two to reveal the spiral growth of the creature's shell which is visible. The growth cells have filled in with different materials which have become rock over the years - somewhere between 240 - 64 million years ago. Ammonite's became extinct with the dinosaurs.

Another “Ammonite, iridescent,” piece, originating in South Dakota, and seen today in the Houston Museum of Natural Science.
The fossil was captured in Geological Museum in Poland.
The only geological museum in Poland, where you will see a complete collection of rocks, reflecting the geological structure of the country. The thematic exhibitions allow you to delve into the fascinating world of minerals, crystals and fossils. You can also see a mini exhibition of meteorites, as well as the skulls of our prehistoric ancestors. Take a selfie with a Dilaphosaurus, which lived 200 million years ago in the Polish mountains. A faithful copy of this feathered prehistoric reptile known as Dyzio has a loyal group of fans. However, the biggest impression on visitors is made by the skeletons of animals from the ice age: a mammoth, a large rhinoceros and a hairy bear. And all this for free in the beautiful, somewhat old-fashioned interiors of a building from the beginning of the 20th century.
Think I bought this in Nederland Co. Ammonites are perhaps the most widely known fossil, possessing the typically ribbed spiral-form shell as pictured above. These creatures lived in the seas between 240 - 65 million years ago, when they became extinct along with the dinosaurs.
This large example (life sized) has had the calcite covering removed and has been polished to show the beauty of nature revealed.
Predominantly found in Utah - US. A desert state which was covered in water millions of years ago.
The subclass Ammonoidea, a group that is often referred to as ammonites, first appeared about 450 million years ago. Ammonoidea includes a more exclusive group called Ammonitida, also known as the true ammonites. These animals are known from the Jurassic Period, from about 200 million Ammonite Fossil - Cleaned and polished years ago.
This is a beautiful ancient Ammonite fossil. Ammonites are extinct marine molluscs that lived from the early Devonian to late Cretaceous period (400-65 million years ago).

Mary Anning (1799-1847) was a female paleontologist working in the cliff beds along the south coast of England around Lyme Regis. As a woman she could not join the Geological Society, and had to be content with her own research and selling many of her fossil discoveries to survive financially. As a young girl she started finding fossils and this led to an obsession for learning. At age 11 she found a fossilised Ichthyosaur that ended up in the collection of the British Museum. Her story is told in a recent film, "Ammonite". www.youtube.com/watch?v=AnDhlrs3XVM
Cette pièce d'Ammonite fossilisée incrustée de Citrine présente un motif faisant apparaître des formes et des couleurs étonnantes. C'est autant un art naturel qu'un phénomène géométrique et arithmétique à la fois. #Macro #MacroMondays #Shell
