I'm sorry you didn't get responses. The biggest unveiling of dinosaurs to the public was the sculptures by Benjamin Waterhouse Hawkins for Sir Richard Owen at London's Crystal Palace, so that's definitely an area you can look into to look for initial reactions.

Owen coined the term Dinosaur in the 1840s for just 3 dinos, known from incomplete remains, and basically viewed as giant extinct lizards— the early 1800s also saw the discovery of other more-complete giant extinct reptiles such as Ichthyosaurus and Plesiosaurus in the 1820s, and giant extinct mammals like Mammoths and Mastodons had only just been scientifically described in 1799, while Irish Elk and giant ground sloths were being discovered in the early 1800s as well. So while the dinosaurs are by far the most famous of the Crystal Palace sculptures, there are also sculptures of those other extinct giant creatures. At the time dinosaurs weren't necessarily a bigger deal than the marine reptiles— you can note in Jules Verne's 1864 novel Journey to the Center of the Earth, which features the characters encountering giant prehistoric creatures that avoided extinction inside the hollow earth, mammoths and a dramatic fight between a Ichthyosaurus and Plesiosaurus are there, but dinosaurs are absent. So for your question I'd suggest expanding past dinosaurs to also look into the reaction to these other early 1800s extinct animals.

Also note that all of these discoveries preceded Darwin's Origin of the Species, so the existence of giant extinct animal bones wasn't necessarily tied to any religion-challenging theories of evolution or anything in the eyes of the public yet. Mounted dinosaur skeletons displayed in museums and academies of sciences first started cropping up at the end of the 1860s (Hawkins mounted the first one in 1868 in Philadelphia), and as time went on the truly giant and most-famous dinosaurs ('Brontosaurus' in the 1870s, Triceratops in the 1880s, Tyrannosaurus in 1905) being discovered in the US led to dinosaurs absolute supremacy among prehistoric animals and in popular culture.
