Vinctifer comptoni Fossil Value Guide

The Vinctifer comptoni is a remarkable extinct bony fish from the Early Cretaceous period, prized for its three-dimensional preservation. Unlike flattened fossils, these specimens are found within calcareous nodules from the Romualdo Member of the Santana Formation in Brazil.

What affects the value of Vinctifer comptoni Fossil?

• Completeness of the fish skeleton, particularly the delicate snout and tail fin.
• The quality of the limestone nodule split and how well the fossil contrasts against the matrix.
• Overall size of the specimen, with larger, well-articulated examples reaching the $440 range.
• Presence of any preparation marks or restoration that might impact the natural appearance of the fossilized bone.

How to Identify Vinctifer comptoni Fossil?

• Look for the characteristic elongated body shape preserved within a split limestone concretion nodule.
• Verify the origin as the Araripe Basin in northeastern Brazil, specifically the Santana Formation.
• Examine the fossil for 3D structural integrity rather than a flat compression, typical of the Romualdo Member.
• Check for the presence of ganoid scales and a long, slender snout characteristic of this Aspidorhynchid fish.

History of Vinctifer comptoni Fossil

Vinctifer comptoni is an extinct species of bony fish that lived during the Early Cretaceous period. These fossils are predominantly found in the Romualdo Member of the Santana Formation in the Araripe Basin of northeastern Brazil. The Santana Formation is world-renowned for its exceptionally preserved fossils, often found in three-dimensional form within calcareous nodules, which formed rapidly around the organic remains before they could flatten.
