Described By: Benson

Juratyrant was another small tyrannosaurid about 3 meters long from the Kimmeridge Clay Formation of Dorset, England. It lived in the Tithonian age of the Late Jurassic, about 149 million years ago. It is known from partial post cranial remains, making it rather unknown, though it seemed similar in appearance to Stokeosaurus and was originally described as a species of it. It was far smaller than later tyrannosaurs, like most early ones, and it probably ate smaller dinosaurs, juveniles of larger ones, and small mammals, reptiles and amphibians. It is not the first tyrannosaurid known from England (Eutyrannus is) but its still remarkable in being from there. It probably had feathers.

NameSantanaraptor placidus

Name Meaning: Placido’s Santana Formation Thief 

First Described: 1999

Described By: Kellner

ClassificationDinosauria, Saurischia, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Coelurosauria, Tyrannoraptora, Tyrannosauroidea

Santanaraptor was a small theropod, about 1.25 meters long, from the Aptian to Albian ages of the Early Cretaceous, about 108 million years ago. It was found in the Santan Formation of Brazil, which is rare for a tyrannosaurid - as such, its discovery caused quite a stir. It is known from only partial fossils and is definitely a coelurosaur, having similar long arms, three fingers, and slim hindlimbs to Dilong and Guanlong. It is however, still possible that it was a basal coelurosaur, and given the incompleteness of the remains, more should be found before its classification can be confirmed. Some soft tissue was found with the skeleton, with skin and muscle tissue found with some blood vessels.

Tanycolagreus topwilsoni

NameTanycolagreus topwilsoni 

Name Meaning: Wilson’s Long Limbed Hunter 

First Described: 2005

Described By: Carpenter et al

ClassificationDinosauria, Saurischia, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Coelurosauria, Tyrannoraptora?, Tyrannosauroidea?

Tanycolagreus was similar to Coelurus and probably was a tyrannosauroid, though its classification is dubious. It was originally in fact thought to be a specimen of Coelurus, but has since been given its own genus. It was found in Bone Cabin Quarry West, in the Salt Wash Member of the Morrison Formation of Albany county, Wyoming. It lived form the Oxfordian to Tithonian age of the Late Jurassic, about 153 to 150 million years ago. It had a large, elongated head and blunt snout, with long forelimbs and long hindlimbs. It was of similar size and build to Stokeosaurus, making it probable that Tanycolagreus was a tyrannosaurid. It was small and lightweight, about 3.3 meters long as a subadult, making it probable that adults reached 4 meters of length.

DAILY LIGHT LEAK: Set Sail

Location: Treasure Island - San Francisco, CA

Settings: F22, ISO 100, 204 second exposure.

Treasure Island is a man-made island in the middle of the San Francisco Bay. It’s hard for me to imagine how they got all the materials to build an island out in the middle of the bay like this; but there I was atop the highest point of the island overlooking the newly constructed bay bridge below, illustrating a stegosaurus on some weather station’s roof.

Name Meaning: Beautiful Feathered Tyrant 

First Described: 2012

Described By: Xu et al

ClassificationDinosauria, Saurischia, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Coelurosauria, Tyrannoraptora, Tyrannosauroidea

Yutyrannus was a decidedly feathered tyrannosauroid from the Yixian Formaton of Liaoning Province, China. It lived in the Aptian age of the Early Cretaceous, about 124.6 million years ago, and was a relatively primitive tyrannosaurid. It is known from three nearly complete skeletons, an adult, a subadult, and a juvenile. It was a large bipedal predator about 9 meters long and is one of the earliest that resembles the classic tyrannosaur form that we all know and love. It had long, 20 centimeters long filamentous feathers, covering various parts of the body, including the pelvis and the foot, neck, and upper arms. They might have covered the whole body and served in regulating temperature, giving the cold climate of the Yixian (around 10 degrees C/50 degrees F). As it grew, its lower legs, feet and forelimbs grew smaller, while the skull grew more robust and deep. Since two juveniles were found with an adult, its reasonable to suppose that it lived in family groups, and may have even hunted in packs.

Probably the most insane dinosaur fossil I’ve yet had listed for sale at Fossil Era.  An insane hand claw from the recently described giant raptor, Anzu wyliei.  

This raptor from the Hell Creek Formation of South Dakota has been dubbed “The Chicken From Hell" both because of it’s appearance the the name of the formation where it is found.  This claw is 2.66" around the curve (2.48" straight-line) and while it has a few repaired cracks it did not require any restoration.  Raptor hand claws not only are very rare to find complete but get quickly snapped up by collectors if they come up for sale.

The identification of this claw was done by the excavator and lead preparitor on the Anzu type specimen.
