Electrotettix Attenboroughi
''Electrotettix'' is an extinct genus of pygmy locust found in amber collected in the Dominican Republic. Represented by a single species, ''Electrotettix attenboroughi'', which lived 18-20 million years ago, it fed primarily on moss, fungi, and algae. The genus name is derived from ''electrum'', Latin for "amber", and Greek '' tettix'', meaning "grasshopper". The species was named after Sir David Attenborough. The female measures 8 millimeters in length: the male is unknown. The species is distinguished from modern members of the Cladonotinae subfamily by the fact that it retains vestigial wings, a feature lost somewhere between the ancient specimens and more modern species. ''E. attenboroughi'' was identified from a collection of amber at the Illinois Natural History Survey, which had been stored in a cabinet under a sink since it was collected in the 1950s by entomologist Milton Sanderson.

Burdigalian
The Burdigalian is, in the geologic timescale, an age (geology), age or stage (stratigraphy), stage in the early Miocene. It spans the time between 20.43 ± 0.05 annum, Ma and 15.97 ± 0.05 Ma (million years ago). Preceded by the Aquitanian (stage), Aquitanian, the Burdigalian was the first and longest warming period of the MioceneEdward Petuch, Ph.D. Florida Atlantic University, Department of Geosciences. and is succeeded by the Langhian. Stratigraphic definition The name Burdigalian comes from ''Burdigala'', the Latin name for the city of Bordeaux, France. The Burdigalian Stage was introduced in scientific literature by Charles Depéret in 1892. The base of the Burdigalian is at the first appearance of foram species ''Globigerinoides altiaperturus'' and the top of magnetic chronozone C6An. , an official GSSP for the Burdigalian had not yet been assigned. The top of the Burdigalian (the base of the Langhian) is defined by the first appearance of foram species ''Praeorbulina gl ...
