FTIR spectrum of UALVP 53367 (red line). (A) Comparison to oxidized cupressaceous-araucarian Cretaceous Cedar Lake amber (Manitoba), and detailed Recent Cupressaceae resin (Cupressus sempervirens). Hydroxyl groups region underlain in blue. (B) Magnified spectral region 700–1900 cm−1; numbers refer to spectral features mentioned in text; blue marks regions linked to molecular water, yellow marks characteristics of cupressaceous-araucarian resins.
