Comparison of calculated hydrocarbon strain energies using ab initio and composite methods
An evolutionary history embedded in amber: reflection of the Mesozoic shift in weevil‐dominated (Coleoptera: Curculionoidea) faunas
Propagation phase-contrast X-ray synchrotron microtomography was utilized to obtain high quality 3D images for some fossils and, at the same time, permit a concise description of them.

This study provides a fairly comprehensive, though by no means exhaustive, review of baridine external and internal morphology to aid future studies on the Curculionoidea group, particularly in phylogenetics.
A new genus of nemonychid weevil from Burmese amber (Coleoptera, Curculionoidea)
Although several important areas of the body are obscured by the shape and fragmented condition of the amber piece, a sufficient number of features are visible to consider adequate placement within Rhinorhynchinae, including the fairly strongly punctate elytral striae and appendiculate, nearly bifid pretarsal claws.
Dryophthorine weevils in Dominican amber (Coleoptera: Curculionidae)
Two new species of dryophthorine weevils are described and figured from remains preserved in Early Miocene (Burdigalian) amber from the Dominican Republic, indicating that this likely phoretic interaction is at least 19 million years old.
A weevil of the genus Caulophilus in Dominican amber (Coleoptera: Curculionidae)
An orthognathine weevil of the genus Mesocordylus in Dominican amber (Coleoptera: Curculionoidea: Dryophthoridae)
A new orthognathine weevil species (Curculionoidea: Dryophthoridae) is described and illustrated from Early Miocene Dominican amber, which represents the first amber fossil record of Mesocordylus and the second for the subfamily Orthognathinae.

Insect Wings: The Evolutionary Development of Nature’s First Flyers
Powered flight has evolved independently at least four times, three of which occur among the Amniota, while the last is far flung across the branches of the animal tree of life.
