Muonionalusta Meteorite End cut 376grMuonionalusta Meteorite A 4. 5 Billion Year Old Fragment of a Shattered Planetary Core Few objects on Earth carry a history as vast as the Muonionalusta meteorite. Formed at the very dawn of our solar system (approximately 4. 5653 billion years ago) this extraordinary iron meteorite originated in the molten core of an ancient protoplanet that was violently shattered long before Earth's continents existed. The Fall Muonionalusta impacted northern

His efforts in collecting and studying the fossils from Shark Tooth Hill have provided invaluable insights into the Miocene marine ecosystem and have helped to foster a greater appreciation for this unique and historically rich site

and darker mineralized roots

The Widmanstätten Pattern The defining feature of every Muonionalusta specimen is its breathtaking Widmanstätten pattern -an interlocking geometric lattice of kamacite (low nickel iron alloy) and taenite (high nickel iron alloy) crystals that formed as the molten planetary core cooled at a rate of just 1–100°C per million years

Salt Wash Member (upper Morrison)

This authentic Cretaceous dinosaur bone comes from the Lance Formation of Wyoming and is preserved in a small display case for easy showcasing

Fossils are typically found by:

marine mammals

Ontocetus emmonsi

with a chip on the root lobe and on the side of the tooth

A minor chip in the root in the top corner is present but does not detract from the overall aesthetic quality of the tooth

A sleeker shape would reduce drag

with periods of glaciation and interglacial warmth
