ICHTHYOSAURIA of FRANCE
Although not specifically Temnodontosaurus trigonodon / most Ichthyosaurs found in France have been associated with or at times made junior synonyms of T. trigonodon / with the exceptions of specimens 5,6,7 & 9 which are associated with Platypterygius.
I couldn't find a formation named for Lafarge quarry, but this article has a wealth of information about it and the ichthyosaur and associated vertebrates found there:

Note: T. azerguensis had a similar size and postcranial anatomy to other Temnodontosaurus species, however its cranial morphology differed. The rostrum was more elongate and thin and had a reduced quadrate. Since T. azerguensis either had very small teeth or no teeth at all, it has been proposed that it was probably not effective at eating hard shelled or bony prey, and instead had a diet of smaller and softer prey compared to the other Temnodontosaurus species. T. azerguensis is younger than other ichthyosaurs, originating from the bifrons ammiote zone of the middle Toarcian.

When: Early/Lower Jurassic (201.6 - 175.6 Ma)
Environment/lithology: marine; lithology not reported
Note: The validity of the species T. burgundiae has been disputed. In 1995, McGowan proposed Leptopterygius burgundiae should be placed in Temnodontosaurus. The paleontologist Michael Maisch does not see T. burgundiae as belonging to Temnodontosaurus. In 1998, Maisch identified this name as a junior synonym of T. trigonodon. Other specialists recognize T. burgundiae as a species including Martin Sander who described in 2000 specimens from the Toarcian of the Holzmaden area of Germany and from France as being Temnodontosaurus burgundiae.

I am looking for the names of the French formations that the species T. trigonodon has been found in (already know it is the Posidonienshiefer in Germany).Â
