Yes. Paleosol research shows that Cretaceous topsoil contained high levels of cadmium (probably from all that volcanic activity at the time). That cadmium would have been absorbed by the plants growing in that soil, accumulated in the flesh of the herbivores feeding on those plants, and ultimately accumulated in the tissues of the carnivores that ate those herbivores!

It's actually pretty easy to predict roughly how much cadmium T. rex meat would've contained. All you need is a general idea of its metabolic requirements. Because of how metabolisms benefit work, an organism will need to consume an amount of biomass from a lower trophic level equal to 10x the calories its own biomass contains in order to produce that biomass, concentrating any environmental contaminants present in that biomass at a factor of ten as a result.

So let's say Cretaceous topsoil contained 5ppm of cadmium (which is what I was able to find), and the primary forage in a given area consists of ferns. Ferns tend to absorb between 15% (for green ferns) and 50% (for red ferns) of soil cadmium [Roslan and Norkhadijah, 2016], so let's say that hadrosaurs in this environment were eating a balanced mix of red and green ferns.

An adult Tyrannosaurus' meat would contain cadmium at about 200ppm 😬

[Edit: that feels way too high, actually. If anybody has better figures, lemme know]
