Sculda pennata/spinosa and specimens of Sculda sp. The proximal part, the basipod, is difficult to recognise.
Different morphotypes of uropods can be found on several specimens of Sculda.
A smaller morphotype of uropod, which we interpret as an earlier developmental stage in specimens of Sculda sp. of about 0.5 mm in length, differs in certain aspects.
A slightly larger specimen of Sculda sp. also has the three areas developed.
The morphology of the walking limbs (sixth to eighth thoracopod) can only be observed on a single specimen of Sculda sp. The whole limb appears to be tubular, with at least four articles.
In Sculda specimens the telson is more similar to that of extant stomatopods, i.e., it appears stouter and with teeth arranged in bisymmetrical pairs, whereas the shape in palaeo- and archaeostomatopods is more or less elongate triangular with a median unpaired process.
Sculda pusilla, and to small specimens (<15 mm) as Sculda sp. (see table 1 for assignment of specimens to morphotypes or species).
Specimens assigned to the taxon Sculda exhibit preserved pleopods, thoracopods including all four raptorial limbs as well as details of antennae and antennulae.
A single very small and incompletely preserved specimen may be a larva of Sculda sp.. Its uropods appear to have elongate lanceolate endopods and exopods without any teeth or setae, but more than a vague outline is not identifiable.
Massive propodi with blade-like dactyli can also be observed in Sculda sp, i.e., in small specimens.
