caption_attribution_description: English: en:Small shelly fossil en:Yochelcionella interpreted as snail-like mollusc, showing water flow. NB the water flow illustrated here is the opposite of that stated in doi:10.1144/GSL.SP.1989.047.01.04; no source is available for the illustrated interpretation.
context_page_description: Yochelcionella is an extinct genus of basal molluscs which lived during the Tommotian epoch, the first epoch of the Cambrian period. This genus is often reconstructed to resemble snails.
  Yochelcionella is the type genus of the family Yochelcionellidae.
context_section_description: This genus of molluscs possessed shells which were shaped like curved caps, with an exhaust pipe shaped "snorkel" emanating underneath where the apex (point of the shell) curves over.  It is believed that the "snorkel" was used in breathing, allowing waste water to flow away from the gills.
