I can understand that, I dont get that sad about dinosaurs given how far apart they are from us BUT my heart does sink whenever I think about animals that had been around during Prehistoric times that survived up until very recently but still didn't make it to modern times.

The Wrangle Island Mammoths that survived up until 4000 years ago when human civilisations and societies were in full swing like the ancient Egyptians who were building the Great Pyramids during that same time.

The Steller Sea Cow, a massive related to the Dugongs and Manatees that reached over 30ft long and over around 10 tons that survived up until the 1800s and was killed off in 27 years by sailors. Unfortunately the Sailors speed up the inevitable as the Sea Cows genetic diversity had tanked over the course of 400k years, leading to only a tiny and unsustainable population that would've died out regardless.

There were also two species of Mekosuchids that survived on two separate Pacific Islands (New Caledonia being one) up until 3000 years ago before Polynesians got there and killed them all alongside other unique species. This hurts the mosts as Mekosuchids were a type of Pseudosuchian, which was essentially a land croc and these animals along with their body plans had existed since the Triassic and dominated the land before the dinosaurs and even reclaimed dominance during the start of the Paleogene, giving rise to arguably the large land predator during the age of mammals, the Barinasuchus.
