Abstract
SCIENCE SERVICE, Washington, D.C., has recorded an interesting discovery made during the construction of a new road from Tower Falls to Mammoth Hot Springs in Yellowstone National Park. While cutting through a rock, two petrified tree-stumps, both upright as they stood, the report says, millions of years ago, were brought to light. The progress of the new road has left the specimens cut in halves, embedded in the solid rock, which was probably volcanic dust when petrification was taking place during the Miocene period. It is even possible to trace the complicated root systems of the specimens. It has not been decided what species the remains represent. Chestnut, sycamores, sequoias, pines and cypress have all grown in this region during the centuries in which the fossilisation took place.
