The Langenberg locality in Germany, from the early Oxfordian to late Kimmeridgian, displays the variety of plant and animal life from an island ecosystem from the late Jurassic.
During the Kimmeridgian the locality would have been marine, being located between the Rhenisch, Bohemian, and London-Brabant Massifs.
This does not indicate that the taxa present were marine, as the animals and plants may have been deposited allochthonously (albeit only by a short distance) from the surrounding islands.
The sediments to show that there was an occasional influx of fresh or brackish water, and the fossils preserved display that.
There are large numbers of marine bivalve fossils, as well as echinoderms and microfossils present in the limestone of the quarry, although many of the animals and plants were terrestrial.

Many marine taxa are preserved at Langenberg, although they would not have co-existed often with Europasaurus.
There are at least three turtle genera, Plesiochelys, Thalassemys and up to two unnamed taxa.
Actinopterygian fish are abundant, being represented by Lepidotes, Macromesodon, Proscinetes, Coelodus, Macrosemius, Notagogus, Histionotus, Ionoscopus, Callopterus, Caturus, Sauropsis, Belonostomus, and Thrissops.
Also present are at least five distinct morphologies of hybodont sharks, the neoselachians Palaeoscyllium, Synechodus and Asterodermus.
Two marine crocodilians are known from Langenberg, Machimosaurus and Steneosaurus, which likely fed off turtles and fish, and the amphibious crocodilian Goniopholis has also been found.

Conifer cones and twigs can be identified as the araucarian Brachyphyllum, from the terrestrial fossils of the site.
Deposited in the locality are many taxa, including a large accumulation of Europasaurus bones and individuals.
At least 450 bones from Europasaurus were recovered from the Langenberg Quarry, with about 1/3 bearing tooth marks Of these tooth marks, the sizes and shapes match well with the teeth of fish, crocodilians or other scavengers, but no confirmed theropod marks.
The high number of individuals present suggests that a herd of Europasaurus was crossing a tidal zone and drowned.
While the dominant large-bodied animal present is Europasaurus, there is also material from a diplodocid sauropod, a stegosaurian, and multiple theropods.
Three cervicals of the diplodocid are preserved, and from their size it is possible that the taxon was also a dwarf.
The stegosaurian and variety of theropods only preserve teeth, with the exception of a few bones possibly from a taxon in Ceratosauridae.
Isolated teeth show that there were at least four different types of theropods present at the locality, including the megalosaurid Torvosaurus sp.
as well as an additional megalosaurid and indeterminate members of the Allosauridae and Ceratosauria; and there are also the oldest teeth known from Velociraptorinae.

Besides the dinosaurs, many small-bodied terrestrial vertebrates are also preserved in the Langenberg quarry.
Such animals include a well-preserved three-dimensional pterosaur skeleton from Dsungaripteridae, and isolated remains from Ornithocheiroidea and Ctenochasmatidae; a paramacellodid lizard; and partial skeletons and skulls from a relative of Theriosuchus now named as the genus Knoetschkesuchus.
Teeth from dryolestid mammals are also preserved, as well as a docodont, a taxon in Eobaataridae, a multituberculate with similarities to Proalbionbataar (now named Teutonodon).
