| The oolite limestone beds consist of white soft limestones, having at intervals bands of marly clay. |
| The unit is composed of rhythmically bedded marls, horizons of laminated organic-rich black shales, rare marly limestones, clastic turbidites, and penecontemporaneous slumps. |
| I will mock the marly heavens, lamp the purple prairies, I will flaunt my deathless banners down the far, unhouseled lands. |
| The genus obviously preferred environments with slightly deeper water, under quiet, marly sedimentation and a deposition of soft, muddy substrates. |
| The entire formation is between 12 and 20 m thick, and consists of light grey, marly chalk of varying percentages. |
| They are dark marly bands, in which a belemnite, Actinocamax plenus, is found. |
