what dinasaurs??!

sooo a lady at work today asked me a question. (and i have to add she is a fellow christian. shes not a skeptic out to prove christianity wrong or anything like that) sooo the question: why are there no dinasaurs in the bible? they did exist. we have fossils. but science tells us they were on the earth long before man right?? but God created the earth and then man and then animals right?? where are the dinasaurs?? when were they created? when did they live then? hum...
