Baculites Fossil Value Guide

The Baculites fossil is a remarkable 'walking stick' ammonite characterized by its straight, non-coiled shell from the Late Cretaceous period. These specimens are highly collectible due to their unique vertical-movement biology and the frequent preservation of vibrant, iridescent aragonite layers.

What Is Baculites Fossil Worth?

The typical price range for Baculites Fossil is $65 - $72 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• The intensity and coverage of the iridescent ammolite sheen significantly increases market price.
• Specimens retaining clear, intricate suture patterns are more desirable to scientific collectors.
• The length and structural integrity of the segment, as most are found in small fragments.
• The quality of the calcite mineralization within the hollow chambers of the fossilized shell.

How to Identify Baculites Fossil?

• Look for a straight, tapering cylindrical shape rather than the typical spiral ammonite form.
• Examine the surface for complex, leaf-like suture patterns where the internal septa met the outer shell.
• Check for a pearlescent or rainbow-colored sheen on the surface, indicating preserved original nacre.
• Verify the presence of internal chambers often replaced by translucent calcite crystals.

History of Baculites Fossil

Baculites was a genus of cephalopods with a straight, non-coiled shell that lived during the Late Cretaceous period. They are often called 'walking stick' ammonites due to their long, straight shape. These marine predators moved vertically through the water column and are frequently found as partial segments. Some specimens, like this one, retain their original nacre or mother-of-pearl, creating a beautiful iridescent sheen known as ammolite.
