Lithology and environment
| Primary lithology: | red lime mudstone |
| Secondary lithology: | lenticular,current ripples,bioturbation sandy "siliciclastic" |
| Includes fossils? | Y |
| Lithology description: Formed predominately of red limes, with rare thick lenses of terrigenous deposits (Molina and Yebenes 1987) - described as "red clays" by Lapparent (1960). Unit 3: "The coarser terrigenous material (fine to medium sand) is not typically channelized, but most frequently occurs in lenticular bedding and isolated dunes (Diaz et al. 1984)." | |
| Environment: | estuary/bay |
| Geology comments: "Unit 3 is characterized by the disappearance of the carbonate facies and predominance of mudstones. This is interpreted as a muddy intertidal flat deposit...Despite a large discontinuity existing within unit 3, or at its upper or lower boundaries, the intertidal facies can be integrated withing[sic].." terregenous delta-derived material prograding into a shallow lagoon (Diaz et al. 1987). | |

Collection methods and comments
| Collection excludes: | all macrofossils | ||
| Collection methods: | selective quarrying,surface (in situ),mechanical,field collection | ||
| Reason for describing collection: | taxonomic analysis | ||
| Collectors: | J. M. Herrero, A. Lapparent, D. D. Fernández-Galiano | Collection dates: | 2005-2007 |
| Collection method comments: CT-28 was discovered in 2005 and partially excavated 2 years later. The fossils of the 2007 campaign were extracted and deposited in the Museo Aragonés de Paleontología (Teruel, Spain). Several subsequent campaigns discovered new axial and appendicular remains; these new fossils were excavated and prepared but not extracted. | |||
