Spinosaurus is known to have eaten fish and small to medium terrestrial prey as well. [5] Evidence suggests that it was semiaquatic; how capable it was of swimming has been strongly contested. Spinosaurus's leg bones had osteosclerosis (high bone density), allowing for better buoyancy control.
Juvenile spinosaurid fossils are somewhat rare. However, an ungual phalanx measuring 21 mm (0.83 in) belonging to a very young Spinosaurus indicates that Spinosaurus, and probably by extent other spinosaurids, may have developed their semiaquatic adaptations at birth or at a very young age and maintained the adaptations throughout their lives ...
The largest specimen of Spinosaurus cf. aegyptiacus, MSNM V4047, was tentatively assigned to Sigilmassasaurus brevicollis. On the basis of vertebrae, the researchers suggested that Sigilmassasaurus may have grown larger than Spinosaurus. Although in the absence of associated material, it is difficult to be certain what material belongs to which ...
The newest addition to the Field Museum on Chicago's lakefront will give visitors a glimpse of the largest predatory dinosaur yet discovered via a 46-foot (14.02 meter) cast of a Spinosaurus ...
Back in 2014, a team of scientists led by Nizar Ibrahim of the University of Detroit Mercy discovered a partial fossil of a massive spinosaurus in Morocco. What they really needed to find was the ...
A paleontologist called the park “the most important dinosaur dig site in America east of the Mississippi.”
The first fossil was found in 1985 by Ouyang Hui at Pengtang near Jinquan and was reported upon in 1986 by Gao Ruiqi and colleagues, mistaking it for a specimen of Tuojiangosaurus. [1] The type species , Gigantspinosaurus sichuanensis , was described and named by Ouyang in 1992 in an abstract of a lecture. [ 2 ]
MNN GDF 510 to MNN GDF 511 comprise two caudal vertebrae. All of the original Suchomimus fossils are housed in the palaeontological collection of the Musée National du Niger. [1] The initial description of Suchomimus was preliminary. In 2007, the furcula (wishbone)—found during an expedition in 2000—was described in detail. [2]
