The type series was collected from carapace- and appendage-rich surfaces from the upper Cenomanian to lower Turonian (~95 to 90 Ma ago) Churuvita Group, Boyacá, Colombia, between the years 2005 and 2014. Additional nontype material was collected from the Turonian (~90 Ma) Frontier Formation, WY, USA. Specimens from the type series are generally compacted dorsoventrally. However, the thoracic sternites, pleonites, dorsal carapaces, mandibles, and even internal optical structures are represented in three dimensions in some specimens. The specimens were exposed using fine tungsten carbide needles and pin vises, dissecting scalpel blades, and fine pneumatic pencils. Broken or fragile samples were consolidated with the cyanoacrylate adhesive Paleo Bond PB40 and/or stabilized with Paraloid B72 and 95% EtOH as the solvent.
