UA geneticist Taylor Edwards used CyVerse’s data-sharing capabilities to coordinate with his research partners and decipher the data that led to the discovery of the new species.

Shakespeare’s Juliet once famously pondered “what’s in a name,” and the answer would be $100,000 in the case of the recently discovered Goode’s Thornscrub Tortoise (or Gopherus evgoodei in the Latin), a species native to the area of southern Sonora, western Chihuahua and northern Sinaloa, Mexico. A description of the species was published in the journal ZooKeys. (more…)

If two fruit fly species mate, it makes offspring dead or infertile

A University of Utah-led study identified a long-sought “hybrid inviability gene” responsible for dead or infertile offspring when two species of fruit flies mate with each other. The discovery sheds light on the genetic and molecular process leading to formation of new species, and may provide clues to how cancer develops. (more…)

Scientists have identified a new species of ancient porpoise with a chin length unprecedented among known mammals, and suggest the animal used the tip of its face to probe the seabed for food. (more…)

Colossal New Predatory Dino Terrorized Early Tyrannosaurs

A new species of carnivorous dinosaur – one of the three largest ever discovered in North America – lived alongside and competed with small-bodied tyrannosaurs 98 million years ago. This newly discovered species, Siats meekerorum, (pronounced see-atch) was the apex predator of its time, and kept tyrannosaurs from assuming top predator roles for millions of years.

Named after a cannibalistic man-eating monster from Ute tribal legend, Siats is a species of carcharodontosaur, a group of giant meat-eaters that includes some of the largest predatory dinosaurs ever discovered. The only other carcharodontosaur known from North America is Acrocanthosaurus, which roamed eastern North America more than 10 million years earlier. Siats is only the second carcharodontosaur ever discovered in North America; Acrocanthosaurus, discovered in 1950, was the first. (more…)

Scientist names new fly species after the Professor who has supported his work

A Professor from The University of Manchester has had his name immortalised as a new species of fly.

Professor Richard Preziosi, from the Faculty of Life Sciences, said he was delighted with the unusual tribute from researcher Dr Dave Penney.

It follows his continued support of Dr Penney’s unfunded research into amber rocks which he has been investigating for around 20 years.

Dr Penney discovered the new species of fly, which he has named Proceroplatus preziosii, on the Caribbean island of Hispaniola, after finding a fossil in 16 million-year-old amber from the Dominican Republic. His findings were confirmed by Dr Neal Evenhuis, of the Bishop Museum in Hawaii, who is the leading world expert on this group. The species is a tiny gnat just a few millimetres long belonging to the Keroplatidae family. (more…)

Dwarf Species of Fanged Dinosaur Emerges from Southern Africa

A new species of plant-eating dinosaur with tiny, 1-inch-long jaws has come to light in South African rocks dating to the early dinosaur era, some 200 million years ago.

This “punk-sized” herbivore is one of a menagerie of bizarre, tiny, fanged plant-eaters called heterodontosaurs, or “different toothed reptiles,” which were among the first dinosaurs to spread across the planet. (more…)

A new species of dinosaur discovered in Arizona suggests dinosaurs did not spread throughout the world by overpowering other species but by taking advantage of a natural catastrophe that wiped out their competitors. (more…)
