Article Reference Inferring internal anatomy from the trilobite exoskeleton: the relationship between frontal auxiliary impressions and the digestive system
The digestive system of trilobites is rarely preserved. As a result, many aspects of its organization remain unknown. Fortunately, the exoskeleton sometimes preserves evidence of soft-tissue attachment sites that can be used to infer internal anatomy. Among them are the frontal auxiliary impressions (FAIs), probable soft-tissue insertion sites located on the fronto-median glabellar lobe of some trilobites. FAIs are herein described in the Carboniferous trilobite Phillipsia belgicaOsmólska 1970– representing the only known example of such structures in the Proetida and their youngest occurrence. A taphonomic scenario is proposed to explain their variable preservation. Although particularly common in the Phacopina, FAIs or FAI-like structures are also found in several orders that differ greatly. Comparisons with modern analogues suggest that FAIs might represent attachment sites for extrinsic muscles associated with a differentiated crop within the foregut. A review of purported remains of the trilobite digestive system indicates that it usually consisted of a tube-like tract flanked by a variable number of metamerically paired diverticulae. Its anterior portion is not particularly individualized, except in a few specimens that might hint at the presence of a crop. This differentiation of a crop might have constituted a secondarily evolution of the foregut in trilobites, occurring independently in different clades. Accompanied by a strengthening of associated extrinsic muscles, this modification of the foregut might explain the presence of more conspicuous muscle insertion sites on the glabella. Study of FAIs might therefore provide new data on the anatomy of the foregut in trilobites and evidence of diverse feeding habits.

In cities located in environments of high biological importance, urbanization leads to changes in biotic diversity, while monitoring these changes can be difficult. Studies have pointed to the use of metrics that replace species as an alternative. Surrogate models are easily determined measures of biodiversity that correlate strongly with species richness and with what you want to investigate, being useful for detecting or monitoring environmental changes. The use of higher taxonomic levels has been applied to groups of megadiverse organisms, such as arthropods, since difficulties in identifying species are predictable. The aim of this study was to evaluate the practicality of using taxonomic diversity of ants as a surrogate of green area coverage in an urban environment. Four levels of "surrogate resolutions" (subfamily, genus, indicator taxa, and intermediate resolution) were assessed to the taxonomic diversity of ants across three levels of urban green areas (Small = 0 to 35%
