Ammonites and Trilobites

Ammonites are an extinct group of marine invertebrate animals in the subclass Ammonoidea of the class Cephalopoda. Here you will see museum quality fossil ammonites collected from around the world, from Russia, Madagascar, England, Kazakhstan, France, Mexico, Canada, and yes, the USA. They are presented here in 131 premium photographs. Information is provided for each photo.

Trilobites are a well-known fossil group of extinct marine arthropods. They first appeared 525 million years ago, and they flourished for over 270 million years. Trilobites finally disappeared in the mass extinction at the end of the Permian about 250 million years ago. The study of these fossils has facilitated important contributions to biostratigraphy, paleontology, evolutionary biology and plate tectonics. This app presents 49 premium photographs of exotic, museum quality trilobites.

All photographs were taken by Professional photographer Paul Richman of Pixels By Paul in his studio, and optimized for your devices.

Some interesting facts about ammonites and trilobites are also included in the app.

NEW: You can now send physical postcards from within this app to anyone anywhere in the world*. The picture you choose (from this app or from your own Photos library) will be on the front of the postcard. You enter a message and recipient address, and the postcard is printed and mailed. 

This app can entertain in several ways. Its fun to flip through its 4-up browsing screens, and to watch 4-up or 1-up slideshows. Try stretching the images to fill their quadrant (4-up) or screen (1-up), both in portrait and in landscape orientation. And do search through to find and make your favorite wallpaper images.

This app is also intended to spark an interest in ammonites, and begin a learning process that can give a broader perspective of life on earth.

An exclusive feature of all Pixels By Paul apps is their ability to size wallpaper to fit within wallpaper safe areas. Safe areas are the central areas in the Lock and Home Screens that are not blocked by the status bar, date/time bar, unlock slider, and dock. With our apps, you can fit pictures to safe areas while keeping their original aspect (the ratio of height to width is maintained), or you can stretch or squeeze them to completely fill the safe areas.

Stretched images have a reflection at the bottom, so that they fade smoothly behind the bottom controls. You can also wrap images, as in a gallery wrap print. Wrapped images keep their aspect ratio (remain un-stretched), but any surrounding black bars (used to keep the image in the safe area) are filled in with reflections of the image.

You can make such safe area wallpapers from the pictures in this app, and you can do this with your own pictures.
