九佛堂層

九佛堂層（英文：Jiufotang Formation）是位於中華人民共和國遼寧省的地層組，地質年代為白堊紀早期，出土的化石種類包括恐龍、翼龍等，屬於熱河群，其中較著名的物種就包括了小盜龍屬及熱河鳥屬。九佛堂層的確切年代目前仍有爭議，部分研究認為它的地層年代包含侏儸紀晚期至白堊紀早期；透過鈾鉛定年法顯示，九佛堂層的年代為白堊紀早期的阿普第期。 目前僅有部分發現於九佛堂層的哺乳形態類物種有被正式發表命名。 九佛堂層包含了一種尚未發表的大型泰坦巨龍類物種。 義縣層 He, H.Y.; Wang, X.L.; Zhou, Z.H.; Wang, F.; Boven, A.; Shi, G.H.; Zhu, R.X.
