Carcharodontosaur: The Carcharodontosaurs are among the largest carnivores to ever live on Earth! Many species grew to lengths of over 40 feet and weighed in at 8.5 tons, rivaling the infamous T-rex in size! The name means “shark tooth reptiles” referencing the loose similarities between their teeth and those of the Great White Shark. Among the family’s ranks are Acrocanthosaurus, Carcharodontosaurus, and Giganotosaurus! There are two species found in Morocco, Carcharodontosaurus saharicus and Sauroniops pachytholus. Their teeth are often referred to as the “African T-Rex”. Despite this, the two and T-Rex aren’t even remotely closely related. Taxonomically, cats and dogs are more closely related, and they lived millions of years and thousands of miles apart from each other. This tooth is from the Kem Kem Beds of Morocco and is 99 -93.9 million years old.

Ceratopsian: Known as “Horned Dinosaurs”, these plant eating dinosaurs had boney frills on the back of their heads, parrot like beaks, and often (but not always) horns. The most famous is Triceratops. Three Genera of Ceratopsian are known from the Hell Creek formation and this tooth could be one of two, Torosaurus and the infamous Triceratops. Triceratops was a massive herbivore, nearly 30 feet long and ten tons, and roamed North America in large herds 66 million years ago. They fed on tough vegetation, chomping off morsels with their beaks and grinding it down with their teeth. Once a tooth was worn down, they would spit it out and grow a new one, not unlike sharks. This is one of those spit teeth. Its most striking features were the large frill and three large horns, one on its snout and two on its brow, and frill that adorned its head. The brow horns could reach up to four feet in length and the frill three feet across! Torosaurus on the other hand is a rather unusual genus of dinosaur. Fossils are very rare and indicate it would have been very similar to Triceratops, only even bigger! It also had large holes in its frill whose purpose is unknown. Many paleontologists believe that Torosaurus are simply very large mature Triceratops and that they develop the holes in their frill as they age, while many others argue that Torosaurus represents a different genus. This tooth is from the Hell Creek Formation of Powder River County, Montana and is 68 – 66 million years old.

Pterosaur: Known as “Pterodactyls” and “Flying Dinosaurs”, Pterosaurs weren’t dinosaurs at all but were close relatives. They were the first vertebrates to evolve powered flight and would also become the largest with some species having wing spans of nearly 40 feet! Although the wingspan of most species was less than ten feet. Toothed Pterosaurs were generally smaller than their toothless cousins with wingspans rarely approaching 20 feet. This composite tooth is from the Kem Kem Beds of Morocco and is 99 -93.9 million years old.

Edmontosaurus: Hadrosaurs or “Duck Bill Dinosaurs” are large plant eating dinosaurs known for their duck like bills. Edmontosaurus annectens was one of the largest Hadrosaurs growing to 40 feet long and 4.5 tons! They roamed North America in large herds and fed on a variety of vegetation, chomping off morsels with their beaks and grinding it down with their teeth which were packed together in large dental batteries consisting of hundreds of teeth. This tooth is from the Hell Creek Formation of South Dakota and is 68 – 66 million years old.

Titanosaur: Titanosaurs are a group of Long Neck Dinosaurs, aka Sauropods. They are not only the largest of all dinosaurs, but the largest of all animals to ever walk on land! The largest Titanosaurs could reach lengths of over 120 feet and nearly 80 tons! Like other long neck dinosaurs, they were herbivores, stripping leaves with their peg like teeth. This composite tooth is from the Kem Kem Beds of Morocco and is 99 -93.9 million years old.

Spinosaur: Spinosaurus was one of the largest and most bizarre carnivores to ever live on earth! Unlike other carnivorous dinosaurs, Spinosaurus walked on all fours with short hind legs and long arms! Stanger still was its crocodile like snout and large sail on its back for which its named. It was semi-aquatic, living in rivers like crocodiles and feeding on large fish. It grew to lengths of over 50 feet, longer than the infamous T-rex! Traditionally all Moroccan Spinosaurus material has been labeled as Spinosaurus aegyptiacus, however recent discoveries have shown that there might have been several Spinosaurus type dinosaurs. Hence this specimen is labeled as “Spinosaurid”. This restored tooth is from the Kem Kem Beds of Morocco and is 99 -93.9 million years old.

Mosasaur: Mosasaurs are huge carnivorous marine reptiles that lived alongside dinosaurs from 101 to 66 million years ago. Some approached 60 feet (18 meters) in length! They aren't dinosaurs but are close relatives of snakes and lizards. This tooth is from the Phosphates of the Oulad Abdoun Basin of Morocco and is 71 to 66 million years old.

Zarafasaura: Plesiosaurs are a group of large marine reptiles that first appeared a little over 200 million years ago before going extinct 66 million years ago. Though they are often called "swimming dinosaurs", Plesiosaurs weren't dinosaurs at all. Their closest living relatives are believed to be turtles. Like sea turtles, Plesiosaurs had four flippers of similar size. The most famous type of Plesiosaur is the Elasmosaur, known for their small heads and long necks, the long necks being one of the big reasons these animals are confused for dinosaurs. Unlike the herbivorous long neck dinosaur, long neck Plesiosaurs (really all Plesiosaurs) were carnivores and hunted pretty much whatever would fit in their jaws. Zarafasaura oceanis was a medium size Elasmosaur that lived near the end of the Cretaceous period. It grew to lengths of 23 feet and would have fed on small fish and squid using its long pointy teeth. This composite tooth is from the Phosphates of the Oulad Abdoun Basin of Morocco and is 71 to 66 million years old.

Abelisaur: Abelisaurs are a type of meat-eating dinosaur known for their short snout and tall skull which gave them a pug-like face, and their unusually small arms even when compared to other meat-eaters like T-Rex. Their skulls were also very ornate, with numerous small nobs, grooves, and pits. The most famous example of this is Carnotaurus, which also had horns over its eyes. Some Abelisaurs could reach lengths of over 25 feet and weigh over 2 tons! Most Abelisaurs, however, were about 15 feet long, weighed about 900 pounds, and were as tall as an average human. This restored tooth is from the Kem Kem Beds of Morocco and is 99 -93.9 million years old.

Tyrannosaur: Tyrannosaurs are a family of large carnivorous dinosaurs that appeared near the end of the Cretaceous period, the most famous of which being Tyrannosaurus rex. Alongside T-Rex lived a smaller Tyrannosaur named Nanotyrannus lancensis.

Even if you're not a paleontologist, or even a scientist, you've almost certainly heard of T-rex. The monster sized carnivore ruled Late Cretaceous North America with a stubby, two fingered iron fist! Growing to over 40 feet (12 meters) in length and over 15 TONS of muscle teeth and claws!! Unlike other carnivorous dinosaurs, T-rex was extraordinarily bulky and muscular. Although there were some carnivorous dinosaurs who exceeded T-rex in length, comparing them to T-Rex is like comparing a NBA player to a bodybuilder on steroids! This was reflected in its teeth which are much thicker than other carnivorous dinosaur teeth to withstand it's gargantuan bite force, bearing more of a resemblance to serrated spikes than serrated knives. The juveniles were more svelte than the adults, built more for speed than power. It has even been suggested that they would engage in cooperative hunting, the youngsters would use their speed to push potential prey towards the massive jaws of the adults. Like other dinosaurs, T-rex went through multiple sets of teeth in its life time, spitting out an old tooth when a new one was ready to take its place.

Nanotyrannus is a truly fascinating story both evolutionarily and historically. Found alongside its much larger cousin, the infamous T-rex, paleontologist have long debated whether Nanotyrannus is a distinct species or just juvenile T-rexes. This fierce debate continues today, with many paleontologist subscribing to either side. If Nanotyrannus is a valid species, it represents a strange turn in Tyrannosaur evolution. During the last 15 million years of the Cretaceous period, the Tyrannosaurs of North America were getting progressively larger, a process which culminated in T-rex. Nanotyrannus however lived, alongside T-rex and yet was much smaller (about 16 feet long) than the proceeding Tyrannosaurs which it itself evolved from!

This is a partial tooth from either a juvenile T-Rex or a Nanotyrannus from the Hell Creek Formation of Garfield County, Montana and is 68-66 million years old.
