Dinodiplura ambulacra
Exceptional preservation of organisms without hard skeletal parts, like this spider, requires special conditions for fossilization. Spiders appear abruptly in the fossil record. This is a Cretaceous specimen (few cm in size) of Dinodiplura ambulacra from the Crato Formation of Brazil, on display at the Paleontological Museum in Santana do Cariri.
Phasmid
Stick insects (or "phasmids") belong to the Phasmatodea order, which includes the longest insect (up to almost 60 cm in size).
Col de la Croix
View to the east from Col de la Croix. Parts of four stacked nappes are visible from this point: Niesen, Bex, Diablerets and Wildhorn.
Trail Eto River
Harpers Corner, Dinosaur National Monument --- At the floor of these canyons of the Colorado Plateau run the Green and Yampa Rivers.
Pararistolochia goldieana
These large flowers (about 45 cm in size) are produced by the western African plant Pararistolochia goldieana. It is also known as "African corpse flower," because of its intense scent that attracts flies as pollinators. Pollination is an excellent example of interdependence between different organisms. Photo taken by Dr. Oluwole Oyedeji, about 25 km south of Ibadan, Nigeria.
Parallel dinosaur trackways
Three trackways of dinosaur footprints. The middle one was made by a bipedal dinosaur, and those on both sides by quadrupedal dinosaurs (sauropods). The rocky substrate consists of sandstones formed on a beach or coast at low tide. The substrate was originally wet and firm, but deformable. The direction of movement of the dinosaurs was to the left.
Mockingbird
The Galápagos mockingbirds is an insectivorous bird, about 25 cm in size, with brown back, white belly, long tail, and straight, long and thin beak.
Whale-CBL-10
Mysticete fossil whale complete and well articulated. Bones show excellent preservation. Note the flipper bones in the lower central part of the photograph.
Dragonfly
It's not easy to become a fossil... and it's even more difficult if you don't have hard skeletal parts. That is why explaining the exceptional preservation of a dragonfly like this one, on display at the Chicago Field Museum of Natural History, is not a trivial matter. This specimen, from the Eocene of the Fossil Basin, Wyoming, is a few cm in size.
Glacial Erratic at Monthey
The house on the rock was built on an isolated massive boulder. The rock is composed of Mt. Blanc granite, which is not found near this region, and obviously had to be transported for many kilometers by action of glaciers.
