The biggest known petrified tree is a Sequoiadendron giganteum featuring a ______ trunk, located near Coaldale, Nevada, U.S.A.
Show answer Hide answer
Answer: B. 89.9m (295 ft)
Explanation
Notable giant petrified tree specimens, such as those found near Coaldale, Nevada, display massive structural dimensions. Fossilization replaces ancient organic tree tissues completely with silica minerals while preserving intricate cellular details. The enormous trunk measurements confirm that these prehistoric redwoods grew to monumental heights millions of years ago. Petrifaction occurs when buried organic material is slowly saturated with mineral rich groundwater over geologic epochs. Sequoiadendron giganteum represents the giant sequoia species known for producing some of the largest trees on Earth. Paleontological excavations in Nevada uncover these remarkable geological relics embedded within ancient sedimentary strata.
Option A gives seventy nine point five meters which underestimates the documented size of this specific fossil trunk. Option C states ninety nine point five meters exceeding the verified measurements recorded for this Coaldale specimen. Option D incorrectly rejects the accurate measurement option provided among the listed numerical choices.
