Gassendiceras is an extinct genus of ammonoid cephalopods belonging to the family Hemihoplitidae. They lived in the Cretaceous period, Barremian age. [1]
The genus name Gassendiceras honors the French philosopher and scientist Pierre Gassendi (1592 – 1655).
Shells of Gassendiceras species can reach a diameter of about 300 millimetres (12 in). [1]
Fossils of species within this genus have been found in the Cretaceous rocks of southeastern France. [1]
The Barremian is an age in the geologic timescale between 129.4 ± 1.5 Ma and 125.0 ± 1.0 Ma). It is a subdivision of the Early Cretaceous epoch. It is preceded by the Hauterivian and followed by the Aptian stage.
The Hauterivian is, in the geologic timescale, an age in the Early Cretaceous epoch or a stage in the Lower Cretaceous series. It spans the time between 132.9 ± 2 Ma and 129.4 ± 1.5 Ma. The Hauterivian is preceded by the Valanginian and succeeded by the Barremian.
Allocrioceras is an ammonoid cephalopod from the Turonian to Santonian stages of the Late Cretaceous, included in the turrilitoid family Anisoceratidae. Its shell is strongly ribbed and is in the form of a widely open spiral.
Pseudocrioceras is an extinct genus of ammonites. The species Pseudocrioceras anthulai has been found in strata from the Barremian - Aptian age of Chipatá, Santander, Colombia and is known from Georgia and Dagestan. The species Pseudocrioceras duvalianum and Pseudocrioceras fasciculare are found in the Barremian of France.
Crioceras is an extinct cephalopod genus belonging to the subclass Ammonoidea and included in the family Crioceratidae of the ammonitid superfamily Ancylocerataceae. Crioceras is considered by some to be a junior synonym of Crioceratites
Heminautilus is an extinct genus of nautiloids from the nautilacean family Cenoceratidae that lived during the Early Cretaceous. Fossils of Heminautilus have been registered in rocks of Barremian and Aptian age. Nautiloids are a subclass of shelled cephalopods that were once diverse and numerous but are now represented by only a handful of species.
Stoycho Vassilev Breskovski was a Bulgarian paleontologist.
Macroscaphites is an extinct cephalopod genus included in the Ammonoidea that lived during the Barremian and Aptian stages of the Early Cretaceous. Its fossils have been found throughout most of Europe and North Africa.
Gideonmantellia is an extinct genus of basal ornithopod dinosaur known from the Early Cretaceous Camarillas Formation of Galve, Province of Teruel, Spain. It contains a single species, Gideonmantellia amosanjuanae.

This list, 2013 in molluscan paleontology, is a list of new taxa of ammonites and other fossil cephalopods, as well as fossil gastropods, bivalves and other molluscs that have been described during the year 2013.
Hemihoplitidae is an extinct family of ammonoid cephalopods belonging to the superfamily Ancyloceratoidea. Fossils of species within this genus have been found in the Cretaceous rocks of southeastern France, Mexico, Slovakia, South Africa and Trinidad and Tobago.
Hemihoplites is an extinct genus of ammonoid cephalopods belonging to the family Hemihoplitidae. These fast-moving nektonic carnivores lived in the Cretaceous period, from Hauterivian age to Barremian age.
Stenorhynchosaurus is an extinct genus of pliosaurid plesiosaurs which lived in South America during the Early Cretaceous. The type species and only known is Stenorhynchosaurus munozi.
María Euridice Páramo Fonseca is a Colombian paleontologist and geologist. She has contributed on the paleontology in Colombia in the fields of describing various Cretaceous reptiles, most notably the mosasaurs Eonatator and Yaguarasaurus, the ichthyosaurs Platypterigius and Stenorhynchosaurus and the plesiosaur Leivanectes.
Leyvachelys is an extinct genus of turtles in the family Sandownidae from the Early Cretaceous of the present-day Altiplano Cundiboyacense, Eastern Ranges, Colombian Andes. The genus is known only from its type species, Leyvachelys cipadi, described in 2015 by Colombian paleontologist Edwin Cadena. Fossils of Leyvachelys have been found in the fossiliferous Paja Formation, close to Villa de Leyva, Boyacá, after which the genus is named. The holotype specimen is the oldest and most complete sandownid turtle found to date.
Microphorites is an extinct genus of flies in the family Dolichopodidae.
Sachicasaurus is an extinct genus of brachauchenine pliosaurid known from the Barremian of the Paja Formation, Altiplano Cundiboyacense in the Colombian Eastern Ranges of the Andes. The type species is S. vitae.
Antarcticoceras is a genus of crioconic ammonites in the family Shasticrioceratidae. It lived during the Early Cretaceous Period. Antarcticioceras fossils can be found in the Cretaceous rocks of Antarctica and South America.
Wightia is a genus of tapejarid pterosaur recovered from the Lower Cretaceous (Barremian) aged Wessex Formation of the Isle of Wight of England, from which it gets its name. The only species within this genus is W. declivirostris.
