Africa’s ancient crocodiles swim in the Mediterranean Sea to live in Spain’s coastal waters, a new study claims.
Scientists have described fossils of two crocs, approximately 10 feet (3 m) in length, that have probably spread several times across the Mediterranean basin and colonized both Spain and Italy about five million years ago.
Analysis of their cranial bones, isolated teeth and bones – bone plaque on the skin – shows that they belong to the crocodile Chassicia species from ancient Libya and Kenya in Africa.
His remains were excavated between 1995 and 2006 at Venta del Moro near Valencia, Spain, but are now only described in the Journal of Pontontology.
Fossils at this Valencian site are the genus of previously interconnected crocodiles found in the Iberian Peninsula – terrain associated with Spain and Portugal.
They ‘disproportionately’ support the theory that, according to crocodileologists, stretched from Africa to Europe during the late Miocene period, about six million years ago.

Angel Hernandez Lujan at Autonomous University of Barcelona and his team stated, “Our comparisons show that this material is not explicitly related to the diplomat or tomistoma – only two other crocodiles have been described for the European late Miocene period. ”
‘It is likely that this late Miocene species, originally described from Libya and later also identified in Kenya, may spread several times across the Mediterranean basin and colonize the southern regions of Mediterranean Europe .
‘What is most certain is that it will also be located on the coasts of Murcia and Andalucia, although we cannot rule out that it will also spread along the coast of Catalonia and the Balearic Islands.
Millions of years ago, many species of crocodiles of different origins and characteristics inhabited Europe and sometimes even coexisted.
But it was unlikely that crocodiles of the genus Crocodile, which are of African origin, ever lived in the Mediterranean basin.

Descriptions of two crocodiles discovered at the Valencian Venta del Moro site in Spain – excavated between 1995 and 2006 by researchers at the University of Valencia
The remains discovered in the study not only dislike this, but the finding of two partial individuals instead of one may indicate that the entire population was present in the region.
During their ‘colonization’, the reptile spread to the southern regions of the meds, as suggested by Italian regions where fossils have also been found previously – in Gargano, Tuscany and Scontron – over the last few decades.
European territories with late Miocene crocodiles, including the Venta del Moro, were close to the northern Mediterranean coast at the time and therefore easily accessible from seawater.
Crocodile skull photos and drawings from Ventoda Moro remain. Analysis of cranial bones, isolated teeth, and osteoderm (bone plaque on the skin) suggests that they may be related to crocodile species
This idea would be supported by the behavior of modern crocodiles, which are good swimmers and can even reach 19 mph (32 kmph) in water.
An example of this is the current saltwater crocodile (Crocodialus porus), which can form important forts in the open sea to colonize other islands or other continents between Oceania and Southeast Asia.
“All you have to see is how easily it moves in the open sea, in the waters of the Solomon Islands or even in French Polynesia.”
More images from research paper. Images one to four show true alveolar (jawbone), five to 12 show teeth, 13 to 16 show joints, 17 to 20 vertebrae and 21 to 22 osteoderms – scaly deposits
Because of its physical similarity to American crocodiles, the extinct species crocodile chechchiai may be the ancestor of modern saltwater species.
This suggests that crocodiles were able to cross the Atlantic Ocean during the Miocene period, which would explain the presence of the genus in the Americas.
Therefore, in the case of specimens found at Venta del Moro, swimming from the African continent to the European continent ‘should not have been a major effort for them before they reached the peninsula,’ the researchers conclude.
Researchers acknowledged that the remains of the two specimens are too fragmented for a spasm detection because it is of the genus Crocodylus chechiae.
But the morphology of the Vantaa del Moro crocodile is consistent with the state of the ‘crocodile genus,’ researchers.
What was the time of crocodile evolution?
250,000,000 BC -Xilousuchus
Three feet long. 5-10lbs. Lived in the marshes of East Asia. Small animals. Fan-like ‘Pal’ bowls on his back. Divided into pre-historic crocodiles and early dinosaurs.
228,000,000 BC – Phytosaur
Survive during the Early Jurassic period. Most are related to crocodiles. Vegetarian. The modern-day crocodiles looked like – except their nostrils were located at the top of their head rather than at the top of their muzzle.
200,000,000 BC – Eryptosuchus
Bipedal. They did not resemble modern crocodiles in behavior or body shape except for the shape of the head.
110,000,000 BC – Sarcosuchus
Middle Cretaceous period. 40 feet long. 10-15 tons. Eating Dinosaurs and Fish. Lived in the rivers of Africa. This is the odd spread on the muzzle. Seen and behaved as if it were modern decadents, but it was twice as long and about 10 times heavier.
100,000 BC – Stomatosuchus
It is 36 feet long. Ten tons. Ate plankton and krill with its high pelvic-like jaw.
80,000,000 BC – Beyinsochus
Greek for terrible crocodiles. Lived in the rivers of North America. About 33 feet long and 10 tons. They had a 6-foot. Long skull. Fed on fish, shell fish and land creatures. Evidence in fossils suggests that they attacked large North American atrocities.
70,000,000 BC – Champasorus
Five feet long, 25–50 pounds, ate fish and lived in the rivers of North America and Western Europe. Long narrow profile and a tooth studded muzzle. The Cretaceous-Paleogene that killed three-fourths of plant and animal species on Earth survived the extinction event.
65,000,000 BC – Cretaceous-Paleogene deletion event
Non-avian dinosaurs were eliminated and more than half of the world’s species were dispensed. This mass deletion led to the rise of mammals and the presence of humans.
55,000,000 BC – Crocodylidae (modern day crocodiles)
Modern day crocodiles – including saltwater, indigo and American variants – spread worldwide. Although it looks prehistoric, it is a highly developed and complex organism that is a successful predator.
23,000,00 BC – Quinkana
Nine feet long, 500 pounds. Red meat intake in woodlands. Long curved teeth and long legs as opposed to the short legs of the modern curve. These crocodiles become increasingly smaller due to environmental changes.
4,200,000 BC – Crocodylus tharbarnarsoni
It is a very close relative of modern-day crocodiles. Large skull and small bulging rim in front of eyes. Prayed quickly on humans. Lived in the Turkana Basin in Kenya. The largest known true crocodile may be.
