Perisphinctes sp Ammonite Madagascar Jurassic Period (199.6 to 145.5 million years ago) Perisphinctes is an extinct genus of ammonite cephalopod. They lived during the Late Jurassic Epoch, and serve as an index fossil for that time period. Shells of species belonging to this genus have been found in the Jurassic of Antarctica, Argentina, Chile, Cuba, Egypt, Ethiopia, France, Germany, Hungary, India, Iran, Italy, Japan, Madagascar, Poland, Portugal, Russia, Saudi Arabia, Spain, Switzerland, the United Kingdom and Yemen. Kingdom: Animalia Phylum: Mollusca Class: Cephalopoda Subclass: †Ammonoidea Order: †Ammonitida Family: †Perisphinctidae Genus: †Perisphinctes -
@oilshale, any idea what species is this Madagascar fish? Only this half of the module is available, and it’s broken.

Hello, a few months ago I recieved a fossil from the mines from Madagascar; a Barasaurus ( Perm ) It took a lot of trial and error to prep this fossil and I had to keep gluing parts that got lose. the matrix was very challenging, sometimes extrmely hard, and sometimes very soft end the bones were brittle. the fossil was a real challenge, but I got to the end.

All I know is that they may be from Madagascar - any help identifying the type of fish and age would be great. Triassic perhaps? I'm afraid I have no more information. Thank you!

Icarealcyon malagasium Beltan, 1984 Early Triassic Dienerian Sakamena Formation Ambilobe Madagascar Due to its enormous pectoral fins, Icarealcyon malagasium was described by Beltan as a "poisson volant" - a "flying fish" - in the family Semonotidae (not related to what is now known as "flying fish" - these are Exocoetidae in the order Beloniformes). You would expect flying fish to be fast swimmers - the rather thickset appearance of Icarealcyon more likely hints to slow swimmers with relatively high maneuverability (comparable to Albertonia from British Columbia). -

Can anyone ID these dinosaur fossils from Ambondromamy, Madagascar
-Andy- posted a topic in Fossil ID
Hi all, a seller recently offered this dinosaur claw and tooth to me from Ambondromamy of Madagascar. Truth be told, I know next to nothing about dinosaur fossils from this region besides there being massive predatory reptiles there. I was hoping someone could shed some light on what these could be. I am not even sure if the claw is dinosaurian. Thank you.

An ammonite from the Cretaceous of Madagascar, what species?

Cleoniceras sp. Ammonite, polished Madagascar Cretaceous Era (70 to 140 Million years ago) Cleoniceras is a rather involute, high-whorled hoplitid from the Lower to basal Middle Albian of Europe, Madagascar, and Transcaspian region. The shell has a generally small umbilicus, arched to acute venter, and typically at some growth stage, falcoid ribs that spring in pairs from umbilical tubercles, usually disappearing on the outer whorls. 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".

Never seen one like this before.
caldigger posted a topic in Is It Real? How to Recognize Fossil Fabrications
Saw this on our favorite auction site. The only description is "ammonite from Madagascar". Something seems real funky about this guy. Is it carved to look like this? I have never seen one that has flattened out whirls like this.

Douvilleiceras sp. "Tractor" Ammonite Mahajanga Province, Madagascar Cretaceous Age (~58 Million Years Ago) 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. The name 'ammonite' (usually lower-case) originates from the Greek Ram-horned god called Ammon. Ammonites belong to a group of predators known as cephalopods, which includes their living relatives the octopus, squid, cuttlefish and nautilus. Douvilleiceras is a genus of ammonites from the Middle to Late Cretaceous. Its fossils have been found worldwide, in Africa, Asia, Europe, and North and South America.
