Skull morphology and histology indicate the presence of an unexpected buccal soft tissue structure in dinosaurs. [PDF]
J AnatA combined approach of osteology and histology was used to examine the cheek regions of dinosaurs. Strong evidence was found for a soft tissue in this region connecting the zygoma to the mandible, here named the ‘exoparia’. Abstract Unlike mammals, reptiles typically lack large muscles and ligaments that connect the zygoma to the mandible.

Systematic Entomology, Volume 47, Issue 1, Page 13-35, January 2022., 2022 We employ phylogenomic markers (UCEs) to reconstruct the most extensively sampled phylogeny to date for the ecologically dominant leaf‐cutting ant genus Atta, the major herbivore of the New World tropics. The ancestor of Atta arose 8.5 Ma in the North/Central America + NW South America range, and its descendant species rapidly radiated into Neotropical

Phylogeography of Agathistoma (Turbinidae, Tegulinae) snails in tropical and southwestern Atlantic
Zoologica Scripta, Volume 51, Issue 1, Page 76-90, January 2022., 2022 Abstract The rocky intertidal gastropods Agathistoma viridulum and A. hotessierianum occur from the Caribbean to southern Brazil, with a gap in the equatorial region, giving them an anti‐tropical distribution. We used sequences from mitochondrial genes to elucidate the phylogeography of A. viridulum and A.
