Hymenocarina. Despite the head shield being portrayed

Erjiecaris Is an extinct genus of bivalved Cambrian arthropod, known from the Chengjiang Biota of Yunnan, China. It is only known from a single species Erjiecaris minisculo. Around 1 centimetre (0.39 in) long, It has an unusual flattened head-shield, with an elongate body with at least 19 segments and a forked tail similar to Waptia. Unlike most bivalved arthropods, its simple, unstalked eyes are placed on top of the headshield. It was likely a nektobenthic deposit feeder. The relationship of Erjiecaris to other arthropods was considered uncertain in its original description. A later study suggested it was a member of Hymenocarina. Despite the head shield being portrayed as flattened in most specimens, this is likely a preservational artifact from the valves being “butterflied” out, and Erjiecaris likely looked more similar to other hymenocarines.

Pago Casa del Blanco is a Spanish winery in Castilla–La Mancha, Spain. The winery uses the Vino de Pago wine appellation, a classification for Spanish wine applied to individual vineyards or wine estates, unlike the Denominación de Origen Protegida (DOP) or Denominación de Origen Calificada (DOCa) which is applied to an entire wine region. The Pago Casa del Blanco winery was formed as a Vino de Pago in 2003, and geographically it lies within the extent of the La Mancha DOP. The winery in fact sells wine under the Vino de Pago appellation as Pago Casa del Blanco, and under the I.G.P. \"Vino de la Tierra de Castilla\" appellation.
