Good News!

Saint Charles Borromeo is praying for me.

On the url "palaeocritti.com" you find nothing, domain is up for sale, and the guys who did it haven't paid for it.

HOWEVER, this does not delete their materials.

Same site is actually available under a longer url. As I found out while looking at Aelurosaurus felinus.

https://sites.google.com/site/palaeocritti/by-group/gorgonopsia/aelurosaurus

And classification by location is also there:

https://sites.google.com/site/palaeocritti/by-location

Parallel work is also done by this site:

https://sites.google.com/site/paleofieldguide/by-country

My back up blog was not necessary, but it was a good exercise for me!

Mission failed

I now see that the original palaeocritti site has gone down.

Only FEW of the material have been saved onto this blog.

I wanted to check if land dinosaurs had been found in Holy Land, Elasmosauri had, but these are sea reptiles.

Palaeocritti was the site to consult, I had not yet done Holy Land in this salvage blog. Now it is too late./HGL

Carcharodontosaurus saharicus + iguidensis

Carcharodontosaurus was a large meat-eating theropod from the Early Cretaceous of Africa. Its huge skull with powerful jaw equipped with long serrated teeth make it a formidable predator. Carcharodontosaurus was originally described by French paleontologists Deperet and Savornin in 1925 as a species of Megalosaurus from fragmentary remains found in the desert of Algeria. The name Carcharodontosaurus was coined by Stromer in 1931. The original material was destroyed during WWII but additional fossils were found later. In 2007, Brusatte and Sereno described a new species from Niger, C. iguidensis.

Kaprosuchus saharicus

Kaprosuchus is known from only a single almost complete skull discovered in Niger. This crocodyliform was nicknamed "boar croc" after its unusual caniniform teeth which resemble those of a boar. It has been estimated that Kaprosuchus may have reached lengths of 6 metres. It is thought that this crocodyliform would have been strictly a terrestrial (living on land) animal and certainly a feared predator!

Name

Kaprosuchus saharicus

Authority

Meaning of generic name

Kapros, boar (Greek); souchos, crocodile (Greek).

Meaning of specific name

Sahara, Sahara Desert; -icus, belonging to (Greek).

Size

Body length: 6 m , Skull length: 50 cm

Remains

Holotype (MNN IGU12): nearly complete skull.

[Body length calculated, skull length actually measured, most of it at least: photo does not look like back of skull is there, but that might be because I know too little of croc skulls in general.]

Age and Distribution

Horizon: Echkar Formation, Tegama Series; Upper Cretaceous (Cenomanian).

Locality: Iguidi, Agadez District, Niger.

Classification

Crocodylomorpha Neosuchia Mahajangasuchidae.

Suchomimus tenerensis

This large theropod from Niger was very similar to Baryonyx to the point that some author placed it in the same genus. It had an elongated crocodile-like snout equipped with sharp teeth ideal for catching fish. It lived in the similar marshy environments than the modern crocodiles. Blade shape vertebral spines form a low sail over the hips.

Spinophorosaurus nigerensis

Spinophorosaurus is a basal sauropod from the Middle Jurassic of Niger. Known from two almost complete skeletons, it is to date the most complete basal sauropod discovered. It has a number of features that make it a close relative of the Asian basal sauropods such as Shunosaurus, rahter than to the Gondwanan genera. Spiky osteoderms found in association with the skeletons were probably placed at the end of the tail in the living animal to serve as a defense against predators.

Name

Spinophorosaurus nigerensis
