Bad News

The google site palaeocritti actually is down now.

I click this link:

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

This happens:

Back in November 2016, and a long time after that, the non-payment of the site simply meant one had to use:

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

instead of:

www.palaeocritti.com//by-group/gorgonopsia/aelurosaurus

as previously.

Now, the material itself is gone.

Which is bad for Young Earth Creationists, since it gave access to lots of details which could help to debunk the claims presented as generalities derived from such details.

I wanted to check out T Rex on it, because I remembered it said "30 skeletons" ... Palaeofieldguide is still up, it gives less detail, for T. Rex it says:

Several skeletons

https://sites.google.com/site/paleofieldguide/tyrannosaurus

I did not want to get fooled into not saving it./HGL

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:

Parallel work is also done by this site:

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!

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.

Saharastega moradiensis

Saharastega is the most primitive Temnospondyl from Gondwana related to the Edopoidea, a group that flourished during the Late Carboniferous.

Saharastega lived during the Upper Permian Period and was discovered in the Moradi formation, Northwestern Niger. It is suggested that along with Nigerpeton, Saharastega is the most primitive known temnospondyli and estimated at a length of 1.8 metres (5.9 feet). The rocks entombing Saharastega suggest an aquatic habitat with evidence of an oasis.

Rebbachisaurus was a large sauropod dinosaur that grew to lengths of around 20 metres. This animal had a very long neck, small head and whip like tail, which are all common features of sauropods.

One species is presently recognized, R. garasbae, the type species from Morocco. "R. tamesnensis" from Niger is considered a subjective synonym of Nigersaurus taqueti.

Jobaria tiguidensis

Jobaria was a relatively large primitive sauropod dinosaur with a rather short neck; it reached lengths of around 21 m (69 ft). It was discovered in the fall of 1997 during an expedition to Niger's Sahara Desert, led by palaeontologist Paul Sereno. It was first suggested that Jobaria lived during the Early Cretaceous Period, however later studies show that it lived during the Middle Jurassic Period. A juvenile Jobaria discovered at the site in Niger yielded tooth marks on the ribs, suggesting the specimen was preyed upon, perhaps by the dinosaur Afrovenator.

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.
