Fig. 3 in A partial skeleton of an enantiornithine bird from the Early Cretaceous of northwestern China

Fig. 3. Hypothesized phylogenetic position of CAGS−IG−04−CM−007, based on a parsimony analysis of three nonavian theropod outgroups and 20 avian ingroup taxa in PAUP* 4.0b10 (Swofford 2002). Numbered nodes are as follows: 1, Aves; 2, Pygostylia; 3, Confuciusornithidae; 4, Ornithothoraces; 5, Ornithuromorpha; 6, Ornithurae; 7, Carinatae; 8, Enantiornithes; 9, Euenantiornithes. Note the position of CAGS−IG−04−CM−007 within Euenantiornithes, as opposed to that of another Changma specimen (CAGS−IG− 02−0901; You et al. 2005), as a putative basal enantiornithine.

Supplementary Material: Thermal resetting of the Early Cretaceous volcanic rocks of Low Island, South Shetland Islands, Antarctica

Supplementary material comprising the geochronological and petrographic data compilation used for the above-titled paper submitted to Andean Geology (Bastias-Silva et al., 2024). The Ar/Ar data presented here was obtained at the University of Geneva in 2016. During the preparation of this article and the subsequent revisions required for publication, these ages were recalculated, leading to minor differences between the original source file and the data presented in the manuscript. This dataset includes new, unpublished data, which is discussed in the associated publication. Bastias-Silva et al. 2024.
