Virtual Tour of Eric Seifter's Fossil Museum

On May 17th, members of the MGS and the American Fossil Federation were treated to a virtual tour of MGS VP Eric Seifter's new fossil museum. This tour took place about two years after a devastating fire consumed his house and damaged many of his fossils. The breadth and depth of the specimens on display are staggering. Among the riches are mammoth tusks and teeth; dinosaur teeth, eggs, footprints, and coprolites; fossils from early plants; ancient whale skulls, vertebrae, and teeth; and seemingly innumerable Ecphora shells. This barely scratches the surface. A few screenshots from the tour appear below.

Eric is seen discussing a whale tympanic bulla.

Here a Neadertal skull (a replica) sits beside the skull of a modern human, Homo sapiens (not a replica).

The image below shows a portion of the fossils from the Calvert Cliffs and the Lee Creek Mine that grace one wall.

Finally, here's a view of a few of the Ecphora fossil shells in the museum.

Thank you, Eric.

Tour the Smithsonian's Dinosaur Hall from Home

At the moment, we no longer have access to the wonderful Fossil Hall - Deep Time at the Smithsonian's National Museum of Natural History. All of the marvels of the Fossil Hall are waiting patiently for us to visit once this crisis has passed. But you can enjoy these marvels on one of virtual tours the Museum of Natural History has made available here. The Fossil Hall tour is part of the "permanent exhibits."

Notable Quote

Evolutionary biologist Keith Thomson:

Fossils give us an extended view of life itself, projecting life into a time dimension in which an anthropocentric viewpoint is meaningless.
