I'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

I just finished a new display of self collected Kansas predators. I was inspired my fellow member Terrance Skinners similar display. I love it.

This a great lesson about problems with identification. This is a genuine Cambrian fossil but was identified as "Anomalocaris roulette mouth". Thanks to a member of this forum I was put in touch with Dr Allison Daley from Oxford, a leading Anomalocaris expert from the Burgess Shale. The Doc confirmed to me that it was not Anomalocaris, but Omnidens Amplus, a Cambrian predator worm. I mentioned this to the seller and supplied an article on distinguishing the two, and got the Omnidens for 2\3 price! Love it.

First up, let me say that without the paleontologist Don Miller, I could not have completed this. He provided me with an Ichthyosaur tooth, and I had only showed him this completed set days ago. I am sorry to share that he has just passed away. Here is his obituary > http://www.legacy.com/obituaries/delawareonline/obituary.aspx?n=donald-s-miller&pid=171846695 After watching Nat Geo's Sea Monsters where they declared the Cretaceous Seas to be the most dangerous of all times, as well as surfing the Oceans of Kansas website, I knew I had to create a collection of teeth for myself. This box here took me well over 3 years to compile, and is a result of not just my own work, but the efforts of many of my friends as well. From left to right, top to bottom, the creatures insides include - 1) Mosasaur (Liodon anceps) 2) Pterosaur (Siroccopteryx moroccensis) - Gary Greaser 3) Shell-eating Mosasaur (Globidens phosphaticus) 4) Terrible Crocodile (Deinosuchus rugosus) (actually much closer to an Alligator) - George Williams 5) Crow Shark (Squalicorax pristodontus) 6) "False Mosasaur" (Pachyrhizodus caninus) - Kris (KansasFossilHunter) 7) Ginsu Shark (Cretoxyrhina mantelli) - Richard Benefield (Vertman) 8) "Sabertooth Herring" (Enchodus lybicus) 9) Marine "Crocodile" (Elosuchus cherifiensis) - Veomega 10) Pliosaur (Polyptychodon sp.) - Calvin Chu 11) Ichthyosaur (Platypterygius kiprijanovi) - Don Miller 12) Giant Vampire Squid (Tusoteuthis longa) (this is not a tooth, this is its squid pen) - Kris (KansasFossilHunter) 13) "Bulldog Fish" (Xiphactinus audax) - Richard Benefield (Vertman) 14) "Nessie" (Zarafasaura oceanis) - Joe Aaronson 15) Giant Sawfish (Onchopristis numidus) (this is not a tooth, this is a rostrum tooth) - Han Yang Tan (Han. T)
