Longest-surviving Carboniferous-family insect found in Mesozoic amber
The major lineages of winged insects originated in the Carboniferous and most extant families stemmed 150 Ma later. Until now, no family from the...

Jaw shape and mechanical advantage are indicative of diet in Mesozoic mammals
Jaw morphology is closely linked to both diet and biomechanical performance, and jaws are one of the most common Mesozoic mammal fossil elements....

Alienopterix santonicus sp. n., a metallic cockroach from the Late Cretaceous ajkaite amber (Bakony Mts, western Hungary) documents Alienopteridae within the Mesozoic Laurasia
Cockroaches (Blattaria s. str.) were documented from numerous amber localities around the world, representing both extinct and extant families....

An insight into cancer palaeobiology: does the Mesozoic neoplasm support tissue organization field theory of tumorigenesis?
BackgroundNeoplasms are common across the animal kingdom and seem to be a feature plesiomorphic for metazoans, related with an increase in somatic...

Functional and ecomorphological evolution of orbit shape in mesozoic archosaurs is driven by body size and diet
The orbit is one of several skull openings in the archosauromorph skull. Intuitively, it could be assumed that orbit shape would closely approximate...

Diet of Mesozoic toothed birds (Longipterygidae) inferred from quantitative analysis of extant avian diet proxies
BackgroundBirds are key indicator species in extant ecosystems, and thus we would expect extinct birds to provide insights into the nature of ancient...
