AI Article Synopsis
- - A study examined the anatomical structure of mummified wood and compared it to 15 living species from the Lauraceae family found in China and Malaysia, confirming the fossil wood's connection to a specific extant species.
- - This finding represents the first reliable fossil record of this species in Asia, indicating that it had a limited range in the Late Pleistocene due to climatic factors like increased dryness and temperature fluctuations.
- - The research also noted the presence of larval tunnels made by a specific genus of flies in the fossil wood, which have not previously been identified in this species, suggesting new ecological interactions.
Article Abstract
Anatomical structure of mummified wood of (Lauraceae) from the Upper Pleistocene of Maoming, South China and the woods of 15 extant species of from China and Malaysia were examined. The fossil wood has been convincingly attributed to extant species (Hance) Hemsl. This is the first reliable fossil record of in Asia. The finding combined with the results of Biomod2 species distribution modeling suggest that the range of . in the Late Pleistocene in South China and North Vietnam was very restricted due to increased continental aridity and enhanced temperature seasonality in this region. Thus, modern populations of . in Maoming can be considered as glacial relicts. The mines (larval tunnels) produced by the larvae of flies from the genus Lioy (Agromyzidae, Diptera) were observed in fossil wood under study. These cambial miners have never been reported in .
