化石樹脂來自植物分泌出的樹脂，經地層深埋產生之第一階段聚合反應及第二階段揮發物逸散後硬化變質即有機會形成成熟度更高之琥珀。成熟度一般而言與經歷深埋時間及深度有關，在一定程度上可以指示該化石樹脂的年齡。具有黏性的樹脂有機會使生物被黏附而隨著埋藏過程一起形成化石，在此過程生物體軟組織在化石樹脂中有機會被保存下來，對於了解古代生物形態、行為及過去環境是相當珍貴的標本。
臺灣過去僅有零星化石樹脂發現記錄，除了2023 年發表之臺東利吉琥珀外，大多數樣本並未進行下一步研究。因此本研究使用一件經黃能偉及顏一勤初步報導，產自臺南地區糖恩山砂岩之內含生物化石樹脂標本進行影像學及化學成分分析，並且輔以其他臺灣產化石樹脂共同比較。結果顯示此生物屬於蛛形綱，並且經過熱裂解氣相層析質譜、傅立葉轉換紅外光譜及拉曼光譜分析指出臺南東山、新北瑞芳、嘉義東興和臺東利吉化石樹脂均源自龍腦香科，與印尼及福建漳浦琥珀為相同來源；而指示樹脂成熟度之指標結果顯示所有臺灣化石樹脂均屬於琥珀。
對於進一步了解生物經化石化作用後成分之改變，本研究利用穿透式X 光顯微術以非破壞性方式拍攝緬甸琥珀內羽毛。影像顯示其由直徑約6.75 μm之黑色素細胞構成，而黑色素細胞由直徑約750 nm之嗜黑素體組成。另外在琥珀羽毛碎片傅立葉紅外光譜分析中，僅有P3一個樣本具有代表羽毛之amide I吸收帶訊號，並且1500—1400 cm⁻¹處吸收帶與琥珀吸收帶特徵相似但不完整，可能肇因於羽毛成分在化石化過程中與周圍琥珀基質相互作用所導致。

Fossil resins, are plant secretions that undergo polymerization and hardening through burial and volatile loss. This process can trap organisms, preserve soft tissues and provide valuable insights into ancient life and environments. In Taiwan, fossil resin discoveries are rare, and mostly lacking detailed research. This study focuses on a fossil resin from the Tangenshan Formation in Tainan, initially reported by Neng-Wei Huang and Yi-Ching Yen. The organism found belongs to Arachnida. Analyses show that fossil resins from various Taiwanese locations, including Tainan, New Taipei, Nantou, Chiayi and Taitung, originate from plants of the Dipterocarpaceae family, similar to amber from Indonesia and Zhangpu. And also, all Taiwanese fossil resins are classified as amber.
In the other hand, this study uses transmission X-ray microscopy to non-destructively exam feathers inside Burmese amber, revealing melanocytes about 6.75 μm in diameter with eumelanosomes around 750 nm. Only sample P3 shows the amide I absorption band typical of feathers, with the 1500-1400 cm⁻¹ band being similar but incomplete compared to amber, likely due to interactions during fossilization.
