I'm sorry, but it seems that the information needed to identify the organism most closely related to the Velociraptor is missing from the question. In order to provide a clear and accurate answer, it is essential to have the evidence from the models referred to in the question. Without this evidence, it's challenging to make an informed decision about which organism is most closely related to the Velociraptor.
To give you the best answer, please provide the evidence mentioned in the models so that I can assist you in identifying the organism that is most closely related to the Velociraptor. Once you share that information, I'll be able to guide you effectively through the process of analyzing the evidence and making a well-supported choice.
