Darwin Oltremare

 

Dentro una cupola di vetro e acciaio é rappresentata la Terra del Periodo Cretaceo. In un clima da foresta pluviale, si assiste alla trasformazione della vita sulla terra, dal brodo primordiale al ribollire della materia. Tra alligatori, draghi barbuti, scarafaggi giganti, diamanti australiani, tracce di dinosauro, orchidee e foreste preistoriche il visitatore ripercorre le atmosfere di epoche remote.

 

   

 

 

   The Dinosaurs arrive: A Deinonychus: in the film "A night to the Museum? In the Museum of Natural History in London?NO!. Perfectly inserted in the forest of the Cretaceous one, a Deinonychus of 3 mt will electrify the visitors of Darwin - You Earth had been forgetting for the time exhibiting himself in extremely natural movements.

 

   IL DEINONYCHUS: (Deinonychus antirrhopus)

 

Found again in Asia and North America the rests of these saurischis, carnivorous of middle-small dimensions, they middly go up again to the Cretaceous (135-65 million years ago) .Alti few more than one meter, long from the 2 to the 4 meters, you/they could reach at the most the 75 kilos of weight.
The name Deinonychus, terrible claw, ago reference to the more spectacular anatomical particularity of this dinosaur: the claw great and sharp spropositatamente that arms the second finger of the foot.

 

Light skull with ample hollow and arcs on which you/they stuck powerful masticatory muscles, the Deinonychus had to have a brain very developed that it lodged in an ample cranium. The mouth, maneuvered by powerful masticatory muscles, it contained over 70 strong ready teeth to also lacerate the more resistant animal fabric.

 

The Deinonychus was probably able to reach speed of 50 kilometers the time. The anterior legs, relatively long, they were strong and muscular, and the hand, with 3 fingers endowed with strong claws, it certainly had a function of taking.

 

The back limbs show the classical plant of the fast runners: the femur, less developed of the other bones, it has a particular protuberance for the attack of a muscle that had to allow the rotation of the leg before and 'back.

 

During to attach a prey, the Deinonychus used above all evidently the back legs rotating the sharp claw up to 180º to inflict a deadly hit: upright on an alone leg, the victim tore to pieces kicking with the other, or holding himself seized to her with the anterior legs, he kicked with both the feet, also tearing the hardest skin.

 

It is probable that, besides the deadly weapons of which these dinosaurs were gifted they used the considerable mental abilities to elaborate astute traps and strategies of hunting: gathering more himself in groups individualizes, they were able in fact to also overpower certainly a greater herbivore of them. It is probable, therefore, that the Deinonychuses were predatory intelligent, from the acute sight, extremely agile and reagents, sensitive to many stimuli and able rapid reactions.

Over the dinosaurs             The history of the life on the Earth from the first organic molecule to our days.
THE LIFE IS BORN             Particular environmental conditions allowed the molecules to join in a called fluid environment "primordial broth." The first living organisms are born: bacterias and blue algae.
THE VEGETABLE KINGDOM             The Ferns are the first plants with leaves, they don't possess the flower and they are reproduced through spores. Some arboreal kinds, that you colonized the Earth in the Paleozoic era, survive still in Australia and Indonesia.
GIMNOSPERME             The Conifers are "Gimnosperme", from the Greek it plants to "naked seed." The seeds of the Gimnospermes are not formed inside an ovary that becomes the fruit, but they are naked and prepared on the flakes of a cone (or pine-cone) or a similar structure. Today the most known are the pines and the firs.
Il Ginkgo biloba             The Ginkgo biloba is the only kind survived of a group of very ancient plants.His give roots they are extracted active principles used in erboristeria and in medicine.
L'Araucaria             Very rare conifer and protected by international conventions. Evergreen with leaves of form ovata to thorny point. This particular aspect allows to limit the losses of water and to face hostile climates.
Il Tasso             Leaves and seeds of the Rate are poisonous. The birds are able nevertheless to feed some red berries because not digesting the seed they don't absorb the toxic substances of it.
ANGIOSPERME             With the "Angiosperme" best man for the first time a structure that contains and it protects the seeds: the flower. Today they are the most diffused plants on the Earth. Among the most primitive sons-in-law there are Palms and Magnolias.
The Palm             A lot of kinds of Palms exist, different for form and height. The leaves can be webbed as in the fan palm or pennate as in that from date.
La Magnolia             The Magnolias belong to one of the most ancient families of Angiosperme. The essence extracted by their flowers is more still among the you use in cosmetic.
REIGN ANIMAL             After the Protozoa, constituted by an only cell, animals were developed complexes up to the formation of the first Invertebrates (sponges, jellyfishes, polyps) more and more. The Invertebrates don't possess an inside skeleton.
INVERTEBRATI             The Shellfishes are invertebrate with the body covered by a hard caress. Crabs and shrimps appeared ago around 250 million Â
Echinodermis             The Echinodermis (sea stars, curly of sea...) they have an external skeleton formed by calcareous plates: thanks to this characteristic their fossils are among the more communes.
Fishes             The Fishes were the first Vertebrate (inside skeletal structure) animals. The family of the Ciclidis he differentiated ago 150 million years adapting himself to live in sweet water.
BUGS             The first Bugs without wings 400 million years appeared ago; the Blattes, winged bugs, 100 million years appeared later. The giant Blattes can have an opening haul of 20 cms.
Reptiles             The Reptiles dominated the Earth for over 170 million years and they colonized terrestrial environments, aquatic and airplanes. The Alligators, belonging to the order of the Coccodrillidis, they are the only survivors among the most primitive reptiles.Â
The Lizards             The Lizards are among the group of Reptiles that is mostly diversified beginning from the Cretaceous one. The Pogona or "bearded Dragon" it is a seed-arboreal lizard that he colonizes the arid forests.
The Dinosaurs             The Dinosaurs are evolved by primitive Reptiles. From the form of their tracks you can be understood if the animal walked on two or four legs and from the excrements information you/they can be drawn on the anatomy and on their alimentary habits: herbivorous or carnivorous? The disappearance of the great Reptiles allowed the Mammals to evolve and to differ in a lot of forms up to colonize terrestrial environments, aquatic and airplanes.
BIRDS             The Birds began their evolution in the Cretaceous one, diversifying himself/herself/itself from a particular group of Dinosaurs. Their living narrower relatives are the Crocodiles. Today more than 9000 kinds of these feathered Vertebrates they exist.
MAMMALIAN             The Pachiceto was a mammal that he lived in the zones of border between earth and water; some samples are suited for the aquatic environment beginning the evolutionary trial that has brought the modern Cetacean.
