It was the second genus of radiodont found to possess gnathobase-like structures (abbreviated as GLS) and an atypical oral cone after Amplectobelua.

[1] The type species, Ramskoeldia platyacantha, was discovered in the Chengjiang biota of China, the home of numerous radiodontids such as Amplectobelua and Lyrarapax.

Ramskoeldia is known only from a few frontal appendages, gnathobase-like structures (GLSs), disarticulated smooth and tuberculated plates interpreted as parts of their oral cones, as well as fragments of body flaps and head carapace complex.

Conversely, in R. consimilis, the endites of the distal articulated region are slender and most of them have a length that exceeds the height of podomere to which they attach.

[1] Due to the numerous shared characters with Amplectobelua (e.g. larger endites of podomere 8; irregular oral cone; presence of GLSs), the discovery of Ramskoeldia questioned the amplectobeluid affinity of Lyrarapax, a presumed amplectobeliud genus which lacking characters noted above.
