The fossil material of Chabardella was discovered in the Saint-Louis opencast pit in Montceau-les-Mines, France, which dates to the Stephanian B and C substages of the Late Carboniferous period.
The generic name honors D. Chabard, who was curator of the Muséum d'histoire naturelle d'Autun and therefore in charge of the Montceau-les-Mines fossil collection.
Like other mantis shrimps, Chabardella has raptorial maxillipeds (feeding appendages): the second to fifth segments of the thorax each bear a pair of enlarged thoracopods which would have been used to capture prey.
[2] Smith et al. (2023) conducted a phylogenetic analysis which also placed Chabardella in an unresolved polytomy, and further suggests the incomplete knowledge of Daidal pattoni may have also led to this result.
