Pink Beryl and Emerald Crystals

Emerald is actually a member of the beryl family of gemstones (including aquamarine, heliodor, red beryl, and others), but with a higher number of impurities (known as inclusions), and colored various shades of green by trace amounts of chromium.

While dozens of questionable cures and wards for the plague are known, the royalty of both Europe and Byzantium believed that crushed emerald was the surest ward, and would save them from any plague-related death. This belief went so far as to lead the apothecaries and physicians of sixteenth-century England to release a declaration stating that the inefficacy of gems in both curing and warding the plague was due to improper identification and preparation of gems prescribed, not because the “cure” was simply a ploy on the nobility’s belief that the more expensive something was, the better it was.

New Dimetrodon Discovered by HMNS team (by Houston Museum of Natural Science)

The Houston Museum of Natural Science Paleontology team has discovered an articulated specimen of a Dimetrodon on the Craddock Ranch in Baylor County.

The team named the fossil “Wet Willi”—“Wet” because it was found while excavating a drainage trench for the quarry, and “Willi” for Samuel Williston, a paleontologist and educator who was active at the site 100 years ago. Dimetrodon bones are common in the Craddock quarry, but articulated fossil skeletons, like “Wet Willi,” are extremely rare.

Excavation of the fossil is currently underway. “Wet Willi” will be the star of the Permian section of the Museum’s newly renovated paleontology hall, opening in 2012!
