-Andy- posted a topic in Member CollectionsI've always been fascinated by the Cretaceous sea and its myriad of terrifying carnivores, many that would've made Jaws look meek. After watching BBC's Sea Monsters, I made it my goal to compile a box of sea monster fossils. I started this journey 10 years ago, and finally completed the box recently. Allow me to present my Predators of the Cretaceous Sea collection, and take you on a journey to the most dangerous sea of all times. The box measures 20.25 inches long. Inside are 24 unique predator fossils. I will introduce them from left to right, top to bottom: Rhombodus binkhorsti Age: 70.6 - 66 mya | late Cretaceous Formation: Severn Formation Locality: Bowie, Maryland, USA Size: 1 meters Diet: Molluscs and crustaceans art by Nobu Tamura --------------- Polyptychodon interruptus Age: 105.3 - 94.3 mya | Cretaceous Formation: Stoilensky Quarry stratigraphic unit Locality: Stary-Oskol, Belgorod Oblast, Russia Size: Maybe 7 meters (This is a tooth taxon so size is not confirmed) Diet: Anything it could catch Note: If you consider Polytychodon a nomen dubium, then this is a Pliosauridae indet. art by Mark Witton ----------------- Prognathodon giganteus Age: 70.6 - 66 mya | late Cretaceous Formation: Ouled Abdoun Basin Locality: Khouribga Phosphate Deposits, Morocco Size: 10-14 meters Diet: Everything art by SYSTEM(ZBrushCentral) --------------- Coloborhynchinae indet. Age: 99.7 - 94.3 mya | late Cretaceous Formation: Kem Kem Beds Locality: Southeast Morocco Size: 7 meters (high estimate) Diet: Fish and cephalopods
DD1991 posted a topic in EuropeA forthcoming paper on the largest specimen of Dakosaurus from the UK (Young et al. in press) mentions a number of Dakosaurus specimens found in the Woburn Sands Formation, which leads me to suspect that a number of loose Lower Greensand sediments in SE england may have specimens reworked from Late Jurassic sediments. Are there any other Cretaceous sediments in England that have yielded fossils reworked from Jurassic sediments? Young MT, Steel L, Rigby MP, Howlett EA, Humphrey S. (In press). Largest known specimen of the genus Dakosaurus (Metriorhynchidae: Geosaurini) from the Kimmeridge Clay Formation (Late Jurassic) of England, and an overview of Dakosaurus specimens discovered from this formation (including reworked specimens from the Woburn Sands Formation).
