Cretaceous fossils from Limburg (the Netherlands) and Belgium (B).
Fossilsforever posted a topic in Fossil Hunting Trips
Hello All, Some photo's/images taken after fossil hunting trips to Limburg and Belgium. These are Cretaceous fossils (73 and/or 72-66 million year old, late-late Campanian, early Maastrichtian). For the most part the squid-like Belemnites (Belemnitella sp./Belemnitella junior (Nowak, 1913) or B. mucronata (Von Schlotheim, 1830) and other species (Belemnella sp.). Also Sea urchins (Echnicoroys sp.) and one piece of a Hemipneustes sp. or (possibly) Hemipneustes striatoradiatus (Leske, 1778). Also one oyster Pycnodonte vesicularis (Lamarck, 1806) and one small Sea urchin. Most fossils are found in the ground, in sediment and/or in water ('beek'). Last photo: quarry in Belgium (Cretaceous Chalk sediments). The Echinocorys sp. is incomplete but quite big (my girlfriend found it and was very happy. A quite rare and big fossil from that location Photo 1: Echinocorys sp. and Belemnitella and/or Belemnella sp. Parts of the sea urchin are in flint ('vuursteen'). Echinocorys is one of the most common species of sea urchins (Echinoidea) found in Limburg. Photo 2: Belemnitella junior (Nowak, 1913) and/or Belemnitella mucronata (Von Schlotheim, 1830), piece of Hemipneustes sp., one small Sea urchin (possibly Oolopygus sp. The exact species is possibly Oolopygus pyriformis (Leske, 1778). Photo 3: idem (Belemnitella/Belemnella sp.). One is embedded in chalk. Photo 4: Pycnodonte vesicularis (Lamarck, 1806), Cardiaster granulosus (Goldfuss, 1829), Belemnitella sp. and Belemnella sp. These fossils were found in water and in a field. Photo 5: Quarry at Belgium.- 1 reply

We are intermediate paleontological researchers, historians, -hunters as well as collectors interested in preserving and continually expanding our educational research in the field. Our passion is research, educating our youth, collecting as well as repairing and reconstructing of fossil specimens.

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". Kingdom: Animalia Phylum: Mollusca Class: Cephalopoda Order: †Ammonitida Family: †Cleoniceratidae or †Hoplitidae (disputed) Genus: †Cleoniceras-

4 FOSSIL DINOSAUR SAUROPOD REBBACHISAURUS SKULL TOOTH 1.jpg

Rebbachisaurus Teeth SITE LOCATION: North Africa TIME PERIOD: Cretaceous Era ( 95,000,000 million years ago ) Data: Rebbachisaurus is a genus of sauropod dinosaur of the superfamily Diplodocoidea, estimated at 14 metres (46 ft) to 20 metres (66 ft) in length, and 7 metric tons (7.7 short tons) in weight, that lived during the Early–Late Cretaceous period in Africa about 99 million years ago. This massive four-legged plant-eating animal had a small head, a long, graceful neck and a whiplike tail. Rebbachisaurus is distinguished from other sauropods by its unusually tall, ridged back. The discovery of Rayososaurus, a South American sauropod nearly identical to Rebbachisaurus, supports the theory that there was still a land connection between Africa and South America during the Early Cretaceous, long after it was commonly thought the two continents had separated.
