The long-necked sauropods are a diverse group of dinosaurs. With the hundreds of known species there are, it’s no surprise that their taxonomy can be messy sometimes. How do you tell if specimen X is the same animal as specimen Y if you don’t have matching body parts to compare? How does one determine what should and should not be the same species if our sample of fossils is too low? Taxonomy is quite the unforgiving mistress.
