Tryblidium reticulatum is an extinct species of a paleozoic Silurian monoplacophoran.
This species have been discovered and originally described by Gustaf Lindström from Silurian of Gotland in Sweden in 1880. It lived in shallow water. Lindström's original text (the type description) in the Latin language reads as follows:
Loc. nat. Lansa et alia loca in Fårö, Wialmsudd paroeciae Rute et prope Westöös paroeciae Hall Gotlandiae.
Testa ovalis, oblonga, crassa, modice convexa; apex acuminatus, plerumque decorticatus. Superficies externa testse costis et lamellis latis et elevatis transversim exsculpta. Costae prope apicem minores, approximatae, decussatim reticulatae, scrobiculis minutis disjunctae. Lamellse trans- versae pone mediam testam latae, incrassatae, recurvae et concentricae. Apertura marginibus valde incrassatis et inflexis. Exemplum decorticatum (tab. X fig. 12) picturam monstrat radiis obscuris, longitudinalibus. Impressiones musculares, colore nigro, per sex paria ordinatae, anteriores maximae, anulum formant ovalem, dispositione sua impressionibus Patellae cochlearis simillimae. Pars interior cujusdam impressionis circularis, convexa, in plica singula vel duabus continua. Testa e stratis duobus consistit, intimum tenue, lamellosum, albidum, punctulis angulosis permixtum, ad apicem in aream elliptico-ovalem denudatum. Stratum externum, crassum, e fibrillis verticaliter positis formatur. Superficies aperturae oculo armato puncta minuta praebet. Longitudo testae 43 millim., latit. 31 millim., altitudo 10 millim.
