Vermontcaris was discovered in the Parker Slate lagerstätte of Vermont. The genus name refers to the state in which it was found, while the species name refers to the Montcalm family, who owned the land on which the specimens of this species were discovered.
Vermontcaris had a cephalon with a pair of eyes located on stalks and a large, bivalved carapace. It had a thorax with an estimated over 30 to over 37 segments, each with at least one pair of biramous limbs. The abdomen had 4âÂÂ5 segments without limbs.
