    Lost the lost history of African dinosaurs

    A new type of dinosaur present in the Egyptian desert will highlight Africa's history of missing dinosaurs.

    A few fossils from the last days of the dinosaurs, between 100 and 66 million years ago, have been discovered on the continent.

    Scientists say the dinosaurs, which lived about 80 million years ago, are an "incredible discovery".

    The vegetarian giant was the length of the school bus and weighed about the same elephant.

    She had a long neck and skeletons embedded in her skin.

    The remains of fossilized dinosaurs were discovered during an exploratory expedition by paleontologists from Mansoura University in Egypt.

    The new name is Mansuraus Shahainai, the new species as a critical discovery of science.

    "It was exciting for my students to discover bones after bones," said Dr. Hisham Salam of Mansoura University, who led the research. "Each new element helped us recover who this giant dinosaur is."

    He said he expected the pace of discovery to accelerate in the coming years.

    The path of the development of dinosaurs in Africa has remained a lot of mystery for the last 30 million years or so of the dinosaur era.

    The study was co-authored by Dr. Matt Lamana of the Carnegie Museum of Natural History that his jaw "hit the floor" when he first saw pictures of fossils.

    "This was the Holy Grail," he said. "A well-preserved dinosaur from the end of the dinosaur era in Africa that we paleontologists were looking for a long and long time."

    Dinosaur fossils in Africa are rare because so much land is now covered in lush vegetation, rather than exposed rocks that resulted in dinosaur treasure troves elsewhere.

    There is a large gap in the fossil record during the late Cretaceous period, when continents were coming towards the end of massive geological changes.

    "Africa remains a giant question mark in terms of animals living on Earth at the end of the dinosaur era," said Dr. Eric Gorskak of the field museum, which was published in the journal Ecology and Evolution of Nature.

    "ManasaurusSaurus helps us address long-term questions about Africa's fossil record and aquaculture - what animals are living there, and what other species have been closely associated?"

    Geological disturbance
    During most of the Triassic and Jurassic periods, during the early years of the dinosaurs, the Earth's continents joined together as a single large land mass, known as Bangia.

    During the Cretaceous period, the continents began to separate from each other and transform into the configuration that we see today.

    It is not yet clear how Africa is associated with other wild areas in the southern hemisphere and Europe during this period and to what extent the animals of Africa may have cut off their neighbors to develop along their independent lines.

    By analyzing the anatomical features of his bones, the researchers determined that MansuraSaurus was more closely associated with dinosaurs than Europe and Asia than those found in other South Africa or South America.

    This, in turn, shows that at least some dinosaurs can move between Africa and Europe near the end of the rule of these animals.

    "It appears that Africa was not this strange world missing from the dinosaurs that lived elsewhere," Dr Lamana said. "That at least some African dinosaurs had other close ties to other continents at that time."
    Manuserasaurus belongs to Titanusoria, a group of zero bodies, or long-necked dinosaurs eating vegetarian, which were common during the Cretaceous period. Titanosaurus is famous as some of the largest wild animals on Earth.

    However, psoriasis was relatively small for Titanosaurus, and for the weight of the African bull.

    Its structure is important to being the complete dinosaur specimen discovered to date from the end of the Cretaceous era in Africa. The parts of the skull, lower jaw, neck, posterior paragraph, ribs, most shoulder and forelimb, part of the hind foot, and parts of the skin plates are preserved.

    Dr. Gorskak, instead of being a piece of panorama filling gaps in the history of dinosaurs, is more like a "corner piece". "It's like finding the edge piece that you use to help you figure out what the picture is, that you can build from."

    Dr. Veronica Des Diaz, an expert on Serbian dinosaurs from the Berlin-based Four Natorenkund Museum, said the remains of the cyropobod had previously been found in Tanzania and Madagascar.

    "The important thing about this discovery is that we did not know what kind of late Cretaceous tin from North Africa," she said. "Most of the remains were isolated teeth and bones, and thanks to Mansurusaurus, this is no longer the case."

    "This is just the tip of the iceberg - pointing to the fact that Africa has the ability to detect a much richer fossil record," said Dr. Philip Mannion of Imperial College London.

    "This is just the tip of the iceberg - points to the fact that Africa has the ability to detect a much richer fossil record."

    "It's just an incredible discovery, it's especially because of where it was found," said Dr. Michael Demick, Adelevy University.
