Fig. 9 Diagrams comparing reconstruction of tooth development of euharamiyidans A. Shenshou lui; B. Xianshou linglong; C. Arboroharamiya allinhopsoni; D. A. jenkinsi The reconstruction of S. lui is based on LDNHMF 2001, WGMV-001, JZT-D 061, and JZT-CK 005; X. linglong on V 16707A; A. allinhopsoni on HG-M 017; A. jenkinsi on STM 33-9 The upper teeth of A. jenkinsi were preserved in isolation so that the reconstruction should be viewed as an interpretation of the authors, with references of tooth developments in other species.
