Predatory dinosaur was larger than T. rex, went for swims

Red and orange bones represent either the original Egyptian find or the new skeleton. Yellow bones come from other animals. Only the blue and green bones had to be inferred based on other species.
Model by Tyler Keillor, Lauren Conroy, and Erin Fitzgerald, Ibrahim et al., Science/AAAS

The predatory dinosaur Spinosaurus aegyptiacus isn't famous, but it might have been. Discovered in Egypt in 1912, it had all the ingredients to make for a childhood favorite: enormous size, sharp teeth, and a huge, enigmatic sail running down its back. But the study of Spinosaurus suffered a serious interruption when the only bones of the creature happened to be underneath the payload of a British bomber targeting Munich.

Now, roughly 70 years later, Spinosaurus is back thanks to some additional samples discovered in Morocco. These, combined with images of the original skeleton and a handful of scattered bones found in the intervening years, appear to indicate the creature was a rarity for dinosaurs. It was adapted to an aquatic lifestyle and probably used its jaws and claws to snare fish.

The new skeletal remains include parts of the head, the spinal column, limbs, and extensive remains of the tail. It was found in a fossil bed called Kem Kem, which preserves the remains of a freshwater river system including various fish and sharks. The authors created a 3-D scan of the individual bones and, by filling in the gaps with bones scaled up or down from other samples or close relatives, created a complete model of the animal's skeleton. In total, the animal appears to have been 15 meters (nearly 50 feet) long, which would make it larger than any known Tyrannosaurus skeleton.

Tadpole Nebula, Auriga Constellation Star Stickers

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: envelope sealers, star forming activity, awesome astronomy images, tnitac, tadpole nebula, auriga constellation, new born stars, hot young stars, star nursery, dust clouds, interstellar gas clouds

Galaxies, Stars and Nebulae series An awesome outer space picture featuring the Tadpole Nebula, a star forming hub located about 12000 light years away in the Auriga constellation.
This nebula is brimming with new-born stars, many as young as only a million years of age. It's called the Tadpole nebula because the masses of hot, young stars are blasting out ultraviolet radiation that has etched the gas into two tadpole-shaped pillars, called Sim 129 and130, the yellow forms that seem to be swimming away from the three red stars close to the centre of the picture.

Cone Nebula NGC 2264 Taken by the Hubble Telescope iPad Mini Cases

Resembling a nightmarish beast rearing its head from a crimson sea, this monstrous object is actually an innocuous pillar of gas and dust. Called the Cone Nebula (NGC 2264) — so named because, in ground-based images, it has a conical shape — this giant pillar resides in a turbulent star-forming region. This picture, taken by the newly installed Advanced Camera for Surveys (ACS) aboard NASA's Hubble Space Telescope, shows the upper 2.5 light-years of the nebula, a height that equals 23 million roundtrips to the Moon. The entire nebula is 7 light-years long. The Cone Nebula resides 2,500 light-years away in the constellation Monoceros. Radiation from hot, young stars [located beyond the top of the image] has slowly eroded the nebula over millions of years. Ultraviolet light heats the edges of the dark cloud, releasing gas into the relatively empty region of surrounding space. There, additional ultraviolet radiation causes the hydrogen gas to glow, which produces the red halo of light seen around the pillar. A similar process occurs on a much smaller scale to gas surrounding a single star, forming the bow-shaped arc seen near the upper left side of the Cone. This arc, seen previously with the Hubble telescope, is 65 times larger than the diameter of our solar system. The blue-white light from surrounding stars is reflected by dust. Background stars can be seen peeking through the evaporating tendrils of gas, while the turbulent base is pockmarked with stars reddened by dust. Over time, only the densest regions of the Cone will be left. Inside these regions, stars and planets may form. The Cone Nebula is a cousin of the M16 pillars, which the Hubble telescope imaged in 1995. Monstrous pillars of cold gas, like the Cone and M16, are common in large regions of star birth. Astronomers believe that these pillars are incubators for developing stars.
