I was intending to post a landscape today as I have been down to the beach today but realised that the man-made Groynes were the main focal point of the picture and so would probably be against TN rules. So my landscape will go on TL along with my ruined pier pictures from Brighton and you get an ammonite instead.

Ammonite facts from the discovering fossils website

How did Ammonites evolve?

These sea creatures first appeared 415 million years ago in the form of a small straight shelled creature, known as Bacrites. They quickly evolved into a variety of shapes and sizes including some shaped like hairpins. During their evolution the ammonites faced no less than three catastrophic events that would eventually lead to their extinction. The first event occurred during the Permian (250 million years ago), where only 10% survived. These surviving species went on to flourish throughout the Triassic, however at the end of this period (206 million years ago) they faced near extinction, when all but one species survived. This event marked the end of the Triassic and the beginning of the Jurassic, during which time the number of Ammonite species grew once more. The final catastrophe occurred at the end of the Cretaceous period when all species were annihilated and the Ammonites became extinct. This event apparently coincided with the death of the dinosaurs.

How did Ammonites live?

Ammonites began life as tiny planktonic creatures less than 1mm in diameter. In their infancy they would have been vulnerable to attack from other predators including fish. However, they quickly assumed a strong protective outer shell that would shield their soft interior from damage. Evidence suggests that they gained in size rapidly, with females growing up to 400% larger than the males.

Una entrega con tu sello de siempre Karan... hermosa, extraña e impactante visualmente.
El F14 funcionó muy bien creando un desenfoque posterior y anterior muy agradable con el foco bien captado en el centro de la escena.
La iluminación es un acierto para realzar el efecto buscado.
Cheers!.

A post with your stamp always Karan... beautiful, strange and impacting visually.
F14 worked very well creating a rear and front very pleasant OOF with the focus very well captured in the center of the scene.
The illumination is a success to enhance the looked for effect.
Cheers!.

Hi Karan. Good close up of this fossil and an excellent note. Well presented. Murray.

Lots of detail in this shot and a good quality fossil too.

I think this would have converted nicely to B&W.

These kind of live on today, they're related to Nautilus pompilius pompilius, which first appeared around 550 million years ago and can still be found in the Pacific Ocean. (Sorry don't own a T.V, I read alot!)

Hi Karan,
i sure do like this picture it holds a fascination for me.It is a mathematical spiral of the golden ratio,flowers like the sun flower and numerous things in nature show this ratio.The picture has good focus and detail as it shows what appears to be dust on the fossil.Well done. Bob

Hi Karan,
This is a very origianl post.
I like your proposal of the crop on this Ammonite.
It has cinetism, if you look carefully you can see some kind of vibrations and the curves.
Congratulations and thanks for share.
My best regards,
JM

Hi Karan

This is a very beautiful macro work here from you!
Even if we didn't see another beautiful new landscape, this ammonite draws a wonderful spiral composition and the rather shallow (at least that's how it appears) DOF used here works fantasticly! All the attention is drawn to the cernter of the frame nicely.
The details are also super-sharp and the textures are terrific!
Great work!

Bravo and TFS

Hello Karan a creative composition with fine DOF control and focus nicely placed good contrasty light for detail. tfs rgds Necip

Hi Karan.
What a nice subject for shooting and interesting note. I like the right geometrical shapes of the ammonite, impressive vertical cropping and great POV. Illumination and details allow us to see all features of this nature phenomenon. My compliments and TFS.

Hi Karan,
You have captured this ammonite in a really beautiful way. Light, pov, dof and composition create a wonderful and eye-catching image.
Best regard, José M.
PS. Where I live there are lots of Ammonites in the field.

Hello Karan,
Thanks for this nice and much textured picture. Exposition is so good and what to say about those details? Perfect! I enjoyed reading those notes about it. This is a very good macro with excellent DOF. Thanks,
Claudine

Hi Karan,
Your geographic past came to visit again? :) A wonderful macro with great details and a very good DOF, making the outer edges slightly blured so that the eye is drawn to the center.

Hi Karan

This is a topic I really don't know much about so I appreciate postings like this with interesting photos and notes to help me to learn more about these fascinating organisms. Thanks for sharing it with us.

I like your composition and POV showing the intricate geometric or circular patterns. The colours are natural and the details are well captured. Good control of the exposure ensured excellent contrast while the textures are clearly visible.

Well done and TFS.
Regards
Loot
