School Bus Size Dinosaur Discovered in Egypt

Researchers in Egypt just uncovered a newly
identified long-necked dinosaur known as Mansourasaurus shahinae. This is only the sixth dinosaur species to
be discovered in Egypt. M. shahinae sheds light on dinosaur evolution
on the different continents. Even though it was discovered in Egypt, M.
shahinae had more in common with dinosaurs uncovered in Europe than it did with dinosaurs
found in southern Africa. A skeletal reconstruction of the roughly 80-million-year-old
M. shahinae. The colored bones are those that are preserved
in the original fossil; other bones are based on those of closely related dinosaurs. The left lower jawbone of the newly discovered
titanosaurian dinosaur M. shahinae. The fossil was found in rock of the Cretaceous-age
Quseir Formation in the Dakhla Oasis, in Egypt. Student Mai El-Amir (left) and study lead
researcher Hesham Sallam (right), of Mansoura University, prepare to glue bones of the new
titanosaurian dinosaur M. shahinae in the field. The all-Egyptian field team from the Mansoura
University Vertebrate Paleontology initiative that found and collected the new titanosaurian
dinosaur M. shahinae with the plaster “jackets” containing the fossil skeleton at the discovery
site. From left to right: Hesham Sallam, Yassin
El Saay, Farahat Ibrahim, Mai El-Amir, Sanaa El-Sayed, Iman El-Dawoudi and Sara Saber. Mansoura University student Mai El-Amir brushes
an ulna (forearm bone) that likely belongs to the newly identified titanosaurian dinosaur
M. shahinae. Students Mai El-Amir and Sara Saber excavate
ribs and other bones of the newly discovered titanosaurian dinosaur M. shahinae in the
Sahara Desert in Egypt. The team’s field tents are visible in the
background. The four female members of the all-Egyptian
field team that discovered M. shahinae. From left to right: Mai El-Amir, Iman El-Dawoudi,
Sara Saber and Sanaa El-Sayed. The “jackets” contain the fossil skeleton. Image from the supplementary information of
the paper published in the journal Nature Ecology and Evolution. M. shahinae’s lower jawbone, shown here from
five perspectives. The right scapulocoracoid, or shoulder bone,
of M. shahinae, as seen from the side. The dashed line indicates the probable extent
of the missing portion and is based on complete scapulocoracoids of other titanosaurs, the
researchers said. Mansoura University vertebrate paleontology
student Iman El-Dawoudi shows M. shahinae’s lower jaw to two budding Egyptian paleontologists. Study co-researchers Eric Gorscak (left),
Iman El-Dawoudi (center) and Matt Lamanna (right) study the lower jaw of M. shahinae. “It’s absolutely rare to find dinosaurs in
Egypt, though that situation is beginning to change, thanks mostly to the efforts of
my friend/collaborator Hesham Sallam and his team,” Lamanna told Live Science in an email.
