Only sing dinosaur songs with your children if they are learning about dinosaurs!!

From Music Together, which is sometimes too...earnest.

Music can be a powerful ally in learning nonmusical subjects because words gain meaning and energy when set to music. It is fun to sing songs about dinosaurs when children are learning about them. However, recent research in music-learning indicates that words can distract children from the music, particularly the tonal elements of a song. Therefore, songs without words are an important part of the Music Together curriculum. They allow children to have a more purely musical experience without being distracted by attempts to process language at the same time. This gives the tonal part of their music development a chance to catch up with language development, which is so much more emphasized in our culture.
