New paper: pneumatic diverticula and blood vessels in the neural canals of the toothed birds Ichthyornis and Janavis

Key Points

• Research identifies the role of pneumatic diverticula and vascular systems in the neural canals of two Mesozoic ornithurines.
• The study presents osteological evidence implicating both respiratory and circulatory adaptations in Ichthyornis and Janavis.
• Using detailed anatomical analysis, the research explores the relationship between these structures in ancient birds.
• Findings provide insights into the evolutionary context of respiratory and vascular systems, emphasizing their significance in understanding ornithurine biology.
