Jurassic Jazz

A theme guitar with a story of millions, even billions years old! Yes that's a real meteorite fragment coming towards the surprised dinosaur! Here are a few key words that will be explained as you follow the photo's; Jurassic, Triassic, Coelophysis, Camel-Donga meteorite.................... the woolly mammoth..................

That's Coelophysis trying to get out of the egg, and there's one more that has just managed to make an opening in the egg shell. Coelophysis is one of the earliest known dinosaurs, emerging some 220 million (220.000.000) years ago in the Triassic period, but lived well into the Jurassic period. Small, 2.8 meters long, carnivore (meat-eating), fast on his legs, hollow bones, 100 razor sharp teeth............... the predator dino prototype !

The meteorite on the tailpiece is a piece of The Camel-Donga AEUC-M. Meteorites are named after the place where they are found, this one near Camel-Donga, on the Nullarbor Plain, Western Australia, Australia.
Camel-Donga is not a witnessed fall, but it's pristine condition is evidence that the meteorite must have fallen only recently. The main component of this meteorite is a basalt which was rapidly cooled by extrusion to the surface of its parent body, assumed to be the Asteroid Vesta, located in the asteroid belt between Mars and Jupiter.
Asteroids are material left over from the formation of the solar system about 4.5 billion years ago. (that's 4.500.000.000 years!)
Vesta has an average diameter of 506 km with a thin outer basaltic crust. The huge impact, indicated by the 460 km wide and 30-40 km deep crater on Vesta's south pole, which is believed to have occurred about 4.48 billion years ago, would have sent this material on it's way to us.

Scientists have used radiometric dating to measure the ages of meteorites. The results show ages of around 4,500,000,000 years--about seven hundred million years older than the oldest rocks on Earth.
So it actually took the meteorite fragment 4.5 billion years of space travelling to wind up on a jazz guitar !

The Camel-Donga meteorite on Jurassic Jazz is 100 % crusted; Meteoroids enter the atmosphere at speeds of many miles per second. At those tremendous speeds, the air in the path of the meteorite is severely compressed. This hot air causes the exterior of stony meteoroids to melt. The melted portion is so hot and fluid that it immediately ablates (sloughs off) and new material is melted underneath.
A meteoroid can lose most of its mass as it passes through the atmosphere. When it slows down to the point where no melting occurs, the last melt to form cools to make a thin, glassy coating called a fusion crust.

The 'dinosaur tracks' are found in the fingerboard and on the side of the guitar. They are real 'imprints' , cutting through one layer of wood into another beneath it. Dinosaur footprints are impressed on the Earth millions of years ago.
