English: "Major biological changes among vertebrates, plants, and insects, discussed in the paper, in relation to the C-isotope and T variations recorded during the Carnian (Fig. 1). The most notable pattern that can be observed is a major diversification event that affected many groups in the late Carnian (Tuvalian), i.e., just after the main negative C-isotope excursions that mark the CPE. Most of the amber, which indicates stressed conditions, is dated to the latest Julian when biostratigraphic data allow a good age control (88, 89). Data are summarized from the following literature and the references therein. Trackmaker assemblage variations from (10) are as follows. Dinosauria: red star, detrital zircon age for Santa Maria Formation (Brazil); green star, U-Pb age of Ishigualasto fauna (34, 68, 115, 116). Dycinodonts: (117, 118). Crocodilomorpha: (70, 71). Phytosaurs: (119, 120). Rhynchocephalia: (73, 74). Mammals: (80–82). Turtles: (75, 77–79). Plants: (83). Amber: (88). Insects: (91–93). For the δ13C and T records, refer to Fig. 1. Stutt.
