  1. Rare Fossil Dragonfly Covered in Druzy Calcite - Salton Sea, California
    $0.00
    Dragonfly Calcareous sinter Salton Sea, California Dragonfly : 3.78 X 1.8 in Matrix : 5.2 X 4.5 inches 1 inch = 2.54 cm One of the strangest fossils I've handled, this dragonfly landed near a hydrothermal vent in the Salton Sea of southern California, died, and was preserved in a fine druzy calcite known as "Calcareous sinter"! This type of preservation is typically known from hot springs or limestone caves. These specimens were first discovered on a Smithsonian expedition to the area between 1938-1940. As of writing this, I have found the existence of less than a dozen specimens in museum collections around the world and private hands, 8 of which seem to be in museum collections (Japan, Ireland, California UCMP, Smithsonian, Minnesota, Texas Museum of Entomology, Oregon), the others are held privately.

  4. 2 Plumulites Feathery Armored Worm Fossil Annelid - Morocco
    $160.00
    Plumulites tafennaensis (Chauvel, 1967) Extinct Armored Worm Ordovician Period - 450 millions years ago Ktaoua Formation, Kaid Rami, Morocco Plumulites 1 : 1.97 x 0.91 inches Plumulites 2 : 1.92 x 0.86 inches 1 inch = 2.54 cm The soft-bodied preservation of this specimen is fantastic and the iron oxidation causing the orange color gives for a nice contrast to the original matrix. Two complete worms are laying beside one another! Typically these fossils are disarticulated due to the many segments and armored parts, it's incredibly uncommon to find these fossils complete - as the ones from Canada have less than 10 known complete specimens - these from Morocco seem to be slightly better preserved.

  9. Sumac Leaf Fossil Rhus nigricans from Hawes Quarry Colorado
    $55.00
    Rhus nigricans (Sumac) Age : Eocene (48 Ma) Formation : Parachute Creek Member / Green River Formation Locality : Hawes Quarry, Rio Blanco, Colorado Leaf : 3 x 0.7 cm Sumacs are shrubs and small trees that can reach a height of 3.3–32.8 ft. The leaves are spirally arranged; they are usually pinnately compound, though some species have trifoliate or simple leaves. The flowers are in dense panicles or spikes 2.0–11.8 in long, each flower very small, greenish, creamy white or red, with five petals. Sumacs propagate both by seed (spread by birds and other animals through their droppings), and by new shoots from rhizomes, forming large clonal colonies. Learn More
  10. RARE Pronemomobius smithii Cricket Fossil from Hawes Quarry Colorado
    $150.00
    Pronemobius smithii (Cricket) Age : Eocene (48 Ma) Formation : Parachute Creek Member / Green River Formation Locality : Hawes Quarry, Rio Blanco, Colorado Cricket : 4.7 x 1 cm Pronemobius had a body that was somewhat flattened and had long antennae. Since the Eocene period was one of the hottest times in the earth's history, Pronemobius would most likely have been able to lay its eggs quite often. The area of the Green River Formation (Wyoming, Colorado, and Utah) was very warm in the Eocene. Palm trees grew there and the environment was quite tropical. In a detailed study, researchers at the University of Colorado scoured more than 500 museum drawers of Green River fossils for crickets and katydids with intact from legs, looking for evidence of ears. Their analysis indicated that these insects had developed extremely sensitive ultrasonic hearing by at least 50 million years ago. The researchers determined that crickets, moths, and other flying insects have ultrasound-sensitive hearing and can hear bats coming, diving, or swerving in mid-flight to avoid being eaten. Crickets and katydids have ears on their front legs, just below their knees. Insects that evolved such super-sensitive hearing would have had a crucial survival advantage, the researchers said. It is thought that the big evolutionary trigger for the appearance of hearing in many insects is the appearance of bats. Prior to the evolution of bats we would expect to find ears in relatively few insects. Learn More
