500 teeth


Age: a hundred and ten million years previous

Location: Niger


Nigersaurus could be a 30-foot-long phytophagic archosaurian reptile that lived 110 million years past in what’s currently Niger’s desert Desert. Nigersaurus lived during a lush surroundings aboard the predatory dinosaur Suchomimus, the plant eaters ouranosaurus and lurdusaurus, and supercroc. Nigersaurus had a fragile bone and an {especially} wide mouth lined with teeth especially tailored for browsing plants on the point of the ground. This bizarre, long-necked dinosaur is characterised by its unco broad, straight-edged muzzle tipped with over five hundred replaceable  teeth. the first fossil skull of Nigersaurus is one of the primary archosaurian reptile bones to be digitally reconstructed from CT scans.

500 teeth dinosaur

flaky five hundred-toothed dinosaur

Our first we tend toek within the field has been spectacular! exceptional discoveries appear to be watching for United States of America around each dune. On our first day, we found bones of the long-necked dinosaur Nigersaurus. Nigersaurus, you may remember, we named for bones collected on the last expedition here 3 years ago. This saurischian dinosaur (long-necked dinosaur) has an uncommon skull containing as several as 500 slender teeth. a serious goal of this expedition is to seek out the remainder of this uncommon archosaurian reptile thus we will describe it and reconstruct it for everybody to see.

we tend to are closing in thereon goal quick as a result of we stumbled on a skeleton many days later! This skeleton is lying on its facet with the tail curving upward. The curve of the backbone measures regarding fifteen feet. we tend to fastidiously brushed the sand off the a hundred and ten million-year-old bones and mammary gland channels between the key spaces of the skeleton. shortly we will cowl every area in plaster so the skeleton is transported out of the sector and back to the laboratory.

however that’s not all for Nigersaurus. Chris took United States of America all to a flat space of purple-colored arenaceous rock wherever he had settled the jaw of a baby Nigersaurus—one that will match on prime of a silver dollar! This Nigersaurus was a hatchling, most likely lower than one year from hatching once it died and was fossilized.

a brand new carnivore

whereas walking across a awfully flat area, Gabe created a stimulating find—the bones of a new carnivorous archosaurian reptile lay part exposed at her feet. She brushed away the sand from the higher jaw. close lay a part of the backbone and therefore the hip bones. This was a mean customer—the bones are from a skeleton that will live regarding thirty feet long! we tend to hope to seek out additional proof of this sharp-toothed creature because the field season goes on.

an enormous crocodilian reptile

we tend to have an interest find over simply dinosaurs. we would like to find all animals and plants that when lived on the traditional streams and forests a hundred and ten million years ago. one in all the foremost common fossils we encountered within the 1st week of labor belonged to a colossal crocodilian reptile referred to as Sarcosuchus.

This reptile was so much larger than any living crocodile. judgement from the 6-foot bone we tend to found within the 1st week, we suspect it’s going to have measured over forty feet long! The armor plates on its back measured a foot across. we tend to even arranged  out the team to induce a way of simply however massive this animal was.

Hans has been operating with a crew of Allison and Dave to excavate a brand new site. As we mammary gland round the skull, we uncovered another juvenile skull of constant species lying right next to the big one. They carved  a block of rock that enclosed each skulls, knowing full well that it’d weigh around 600 pounds once incased in plaster.

thus i feel you may agree that the primary week here has been a thriller.
