dyrosaurus phosphatosaurus crocodile skull complete

1997/1/1The first relatively complete specimen of Hyposaurus is that of H. derbianus (Cope, 1886) from the Cretaceous of Pernambuco State, Brazil. The presence of an almost complete lower jaw established the longirostrine nature of the species. Ancient Marine Nigersaurus was named and described in more detail by Sereno and colleagues only in 1999, based on remains of newly found individuals.The same article also named Jobaria, another sauropod from Niger.The genus name Nigersaurus ("Niger reptile") is a reference to the country where it was discovered, and the specific name taqueti honours Taquet, who was the first to organise large-scale

Sarcosuchus

Sarcosuchus (meaning'flesh crocodile' and commonly called SuperCroc, is an extinct genus of crocodyliform and distant relative of the crocodile. It dates from the early Cretaceous Period of what is now Africa and is one of the largest giant crocodile-like reptiles that ever lived. It was almost twice as long as the modern saltwater crocodile and weighed approximately 8 to 10 tonnes. Until

Abstract: New material of a long‐snouted dyrosaurid has been discovered in the Paleocene of Morocco. It consists of a well‐preserved skull with embedded mandible and four dorsal vertebrae. The particularly elongate snout, proportionally the longest of all known dyrosaurids, allows precise identification of this material as Atlantosuchus coupateziBuffetaut, 1979, and presentation of an

OCP DEK-GE 255, a nearly complete specimen, with skull, mandible, and postcranial material (), housed in the geological survey of the OCP in Khouribga, Morocco. Type horizon and locality: The phosphate mine of Mera el Arech, in the Oulad Abdoun Basin, Morocco; from the 'layer 1', according to the miner's terms, corresponding to the early Eocene (Ypresian).

These remains were fragments of the skull, vertebrae, teeth and scutes. In 1964, an almost complete skull was found in Niger by the French CEA, but it was not until 1997 and 2000 that most of its anatomy became known to science, when an expedition led by the American paleontologist Paul Sereno discovered six new specimens, including one with about half the skeleton intact and most of the spine .

The skull is almost complete and lacks part of the right quadrate and quadratojugal (figure 2 a–g). The bone surface of almost all elements is ornamented with pits, shallow grooves and ridges, but not as strongly as in most dyrosaurid taxa (e.g. Chenanisuchus,


DYROSAURUS PHOSPHATICUS CROCODILE FOSSIL SKULL

C00 | Dyrosaurus Phosphaticus Crocodile Skull on Frame, Morocco, Early Eocene • Early Eocene epoch (Ypresian age, 56 to 47.8 million years ago) • Khouribga phosphate deposits, Morocco • Dimensions of frame (width x depth x height): 180 x 10 x 130 cm

Carnegie Museum of Natural History has many type specimens in our collections. A type specimen is the name bearing specimen of a species. That means that that specimen was the first to be identified and named as a unique species. In Dinosaurs in Their Time there are 12 type specimens on display. there are 12 type specimens on display.

The skull is almost complete and lacks part of the right quadrate and quadratojugal (figure 2 a–g). The bone surface of almost all elements is ornamented with pits, shallow grooves and ridges, but not as strongly as in most dyrosaurid taxa (e.g. Chenanisuchus,

Paul Olsen of Columbia's Lamont-Doherty Earth Observatory said he had found the skull of the 212-million-year-old unnamed carnivore exposed in the cut of a roadside in the town of Cheshire. The paleontologist said that the three-inch skull belonged to a delicately boned, 20-inch-long reptile that resembled a small crocodile but ran on long, slender legs.

OCP DEK‐GE 51 is represented by a nearly complete skull, only visible in dorsal view, several isolated skull fragments, and four dorsal vertebrae found in association (Text‐fig. 2). The ventral portion of the skull is not available for study because it is still embedded in the matrix.

We describe a nearly complete skull and unassociated mandible of a new dyrosaurid, Cerrejonisuchus improcerus gen. et sp. nov., from the Paleocene Cerrejn Formation of northeastern Colombia. The skull of C. improcerus has relatively elongate supratemporal fenestrae and well-developed occipital tuberosities, both diagnostic characteristics of Dyrosauridae.

The skull of Caiman crocodilus (FMNH 73711) was scanned at the High‐Resolution Scanning Facility of the University of Texas, Austin in 2002. It was scanned along the coronal axis, and a total of 945 projections was made, each with a thickness of 0.142mm.

One of these includes a lower jaw (specimen identification: MOZ 6140P), and the other (MOZ 6146P) consists of an almost-complete skull and lower jaws (Fig. 1 and fig.S2). The new skull is almost complete and reveals an unusual skull and dental morphology.

A dyrosaurid from the Paleocene of Senegal

We describe a partial dyrosaurid skeleton recently prepared out of a limestone block discovered in the 1930s from Danian strata along the Atlantic coast of Senegal. The specimen, from a single individual, comprises nicely preserved elements of the appendicular and axial skeleton from the abdominal and sacral region, which enables us to refine our knowledge on some postcranial characteristics

This is exemplified by the crocodile Dromicosuchus from around 227 Mya (Carnian/Norian) which has a large skull of around 15 cm and long legs suggesting that it was a fleet runner. Its teeth assume a laterally compressed blade-like form with carinae bearing fine serrations.

Sarcosuchus (meaning'flesh crocodile' and commonly called SuperCroc, is an extinct genus of crocodyliform and distant relative of the crocodile. It dates from the early Cretaceous Period of what is now Africa and is one of the largest giant crocodile-like reptiles that ever lived. It was almost twice as long as the modern saltwater crocodile and weighed approximately 8 to 10 tonnes. Until

2004/4/1Four complete and neat alveoli are preserved. The preserved part of the tooth row contains the hypertrophied tooth and a series of two or three and one-half successive alveoli. The first alveolus is twice the diameter of the other alveoli (31 mm and no more than 15 mm in

2019/8/7Little is known about the long-term patterns of body size evolution in Crocodylomorpha, the gt; 200-million-year-old group that includes living crocodylians and their extinct relatives. Extant crocodylians are mostly large-bodied (3–7 m) predators. However, extinct crocodylomorphs exhibit a wider range of phenotypes, and many of the earliest taxa were much smaller (lt; 1.2 m). This

We considered whether the skull possibly belonged to a very young animal, but the extent and pattern of bone growth and the proportional size of the eye pointed to a mature . With a total skull length of just about 0.6 inches (1.5 centimeters), Oculudentavis pushes against what is considered the lower limit of size in birds: the head still had to hold functional eyes, a brain and jaws.

2012/1/31Crocodyliforms were one of the most successful groups of Mesozoic tetrapods, radiating into terrestrial, semiaquatic and marine environments, while occupying numerous trophic niches, including carnivorous, insectivorous, herbivorous, and piscivorous species. Among these taxa were the enigmatic, poorly represented flat-headed crocodyliforms from the late Cretaceous of northern Africa. Here we
