The Allende meteorite is a 4.5-billion-year-old time capsule. How do we read this ancient history? Join Museum Curator Denton Ebel as he reveals the key: chemical thermodynamics. It’s the same science that explains why it takes longer to boil pasta on a mountaintop than at sea level. Watch.👇

#TrilobiteTuesday has crept up on us again in the dark, twilight waters of the Welsh Ordovician. This one is Trinucleus, a blind trilobite characterized by a pitted fringe along the anterior margin of the cephalon.

It’s Trilobite Tuesday! Growing up to 6 in (15.2 cm) long, the sword-nosed Psychopyge is perhaps the most recognizable trilobite to have emerged from Morocco’s bountiful Devonian outcrops over the last four decades. Few species can rival this trilobite's renown or bizarre Paleozoic appearance.

Here is part of the body of quite a large trilobite known as Paradoxides spinosus. This specimen comes from the Middle Cambrian (Drumian) Jince Formation from the Czech Republic. Paradoxides is one of the largest trilobites known from the Cambrian period.

Spent some time in my prep room for some fossil therapy.
This is an Isotelus roller I found at Flat Run quarry near Mt. Orab, Ohio. I exposed most of the body and the genal (cheek) spine.
I can feel my back loosen up and stress melt away.

This was my son's first complete trilobite - a goldbug!
This is a Triarthrus eatoni from the famous Ordovician Beecher's Bed of New York. This site preserves soft tissues like legs, gills and antennae with pyrite or fool's gold.
