Table 1 in ºop of the food chains: an ecological network of the marine Paja Formation biota from the Early Cretaceous of Colombia reveals the highest trophic levels ever estimated

Table 1. Network values from the Paja Formation, Cayman Islands, Cuba, and Jamaica marine food web networks. S, species, the total number of nodes (species); L, total number of trophic links, as the size of the network; C, connectance; maxPATL, maximum prey*averaged trophic level (PATL), which assumes a predator’s diet fractions are equal across the prey (Williams and Martinez 2008); TL, trophic level; SWTL, short*weighted trophic level; meanSWTL, mean short*weighted trophic level (Dunne et al. 2008, Delmas et al. 2019, and references therein). The network statistics were calculated by using Network3D software (Yoon et al. 2004, Williams 2010). The properties output for the Paja Formation biota and the Caribbean systems are available in the Supporting Information, Table S5
