Fun fact: Palaeontology is a fast moving science. Even a book published only a year ago could have a ton of outdated information.

For example, a paper published about the reevalutation of Troodon as a valid genus was published in 2017. Many books published before then will not have the up-to-date information on Troodon. Even many books published after then may not have completely correct information. Every source can have its issues. Be sure to check when your reference book was published before arguing over what could be a recent development.

The best way to keep your information up-to-date is to find or ask for the actual scientific papers online. For example, here is the 2017 paper that reassigns Troodon's fossil material to other Genera, making Troodon a dubious genus: http://www.nrcresearchpress.com/doi/full/10.1139/cjes-2017-0031
