The lower Famennian conodont biodiversity and zonation at the Ryauzyak Section (western slope of the South Urals)

Key Points

• Conodont biodiversity is significantly lower in the lower Famennian strata, highlighting potential ecological impacts.
• The study observes unique zonation patterns at the Ryauzyak section, enriching our understanding of historical marine life.
• Assessment of fossil records from the Ryauzyak section reveals expansive biodiversity shifts occurred during this time.
• The findings may indicate broader environmental changes that affected marine ecosystems during the Famennian period.
