Whale Eardrum – 11.5 to 12 cm Specimen

Whale Eardrum – 11.5 to 12 cm Specimen
A Rare and Well-Preserved Marine Mammal Bone

This impressive whale eardrum, or tympanic bulla, measures approximately 11.5 to 12 cm in length and represents a rare opportunity to acquire a beautifully preserved anatomical structure from one of the ocean’s most remarkable creatures.

Significance and Anatomy

The tympanic bulla is a specialized bone located within the skull of whales, forming part of their highly evolved auditory system. Unlike terrestrial mammals, whales rely on these dense bones to detect sound vibrations underwater, enabling them to communicate, navigate, and forage over vast ocean distances.

Composed of incredibly dense, mineral-rich bone, whale eardrums are built to withstand the pressures and acoustic demands of the deep sea. While their density increases the likelihood of preservation, complete and undamaged specimens are rare, especially in such excellent condition as this one.

Condition and Rarity

• Size: Approximately 11.5 – 12 cm

• Condition: Excellent – minimal wear, full form intact

• Rarity: High – few specimens of this size and preservation quality are available today

• Scientific Relevance: Demonstrates unique acoustic adaptations in marine mammals

Whether for a natural history collection, museum exhibit, or as a striking educational piece, this whale eardrum offers a compelling look into the biology and evolution of the world’s largest marine mammals. Its rarity and state of preservation make it a standout example of cetacean osteology.
