Ok thanks yes the seller also doesnt believe the matrix is original and I do like the look!

Then I would keep it.  The eggs look real and are in typical condition for french eggs.

Not really just to confirm they were or were not placed there.  But if the seller has already said it's not orginal then you have the answer that they were placed in the matrix.  No need for anything else.  If you like the eggs enjoy them they are a nice pair

Red flag to me!, they look real, but they also look like they where just placed into matrix!

This actually looks pretty typical for crushed eggs.

Thanks everyone for the input, I really appreciate it and I feel much more comfortable with the buy now!

About the location, there are no Upper Cretaceous continental deposits in central France. French dinosaur eggs from this period (mainly Megaloolithus and Cairanoolithus, more rarely Prismatoolithus) come exclusively from the extreme south of the country, from the following five departments : Var and Bouches-du-Rhône in the Provence region, and from Ariège, Aude, and Hérault in the Occitanie region (which brings together the two former regions of Languedoc-Roussillon and Midi-Pyrénées). Complete eggs (often crushed in marls and clays and often better preserved in sandstones) are known in all these departments with the exception perhaps of Ariège (in this department discoveries are rare today).

Without embryo remains inside the eggs it is not possible to assign them to a particular genus. Especially since Hypselosaurus has not been a valid genus since a long time. It's another subject but other titanosaurs are better defined in France : Atsinganosaurus velauciensis from the middle Campanian or from the beginning of the upper Campanian (local Begudian stage) from Velaux in Bouches-du-Rhône, and Ampelosaurus atacis from the lower Maastrichtian of Aude. And there are at least four other species whose description is in progress : a second taxon from Velaux, two taxa of the late upper Campanian of Pourrières in Var (the type locality of the abelisaurid Arcovenator), and a taxon from the upper Campanian-lower Maastrichtian (age uncertain) of Cruzy in Hérault. Some bones suggest the presence of additional species but which are not yet known by sufficient remains to be named.

To compare here some photos from the web of French dinosaur eggs from different localities :
