OMNH 2162, probable dorsal 2 of the big apatosaur

Key Points

• The vertebrae's missing neural spine and transverse process suggest unique morphological features.
• Pneumatic chambers within the vertebrae could indicate adaptations related to respiratory efficiency.
• Observing the condition of cortical bone provides insights into the fossilization process.
• The dorsal orientation of the vertebra helps identify its functional position within the organism.
