I will as a creationist try to deal with this.
But first you must allow me something.
We Don't believe there are transitionals so our defining what they are or look like is,ah,unnatural.
We are told all creatures evolved from one body type to another over great amounts of time.
A deer was, to go back father by father, a rodent like creature and before that something else.
We have elephants, cats, pandas, and millions of years ago thier biological ancesters would be totally different and unrecognizable.
So from that point to this since the process of change happened because of natural selection etc it is concluded that the change of body type must of happened a lot and so fossils of this should be evident. Remembering that fossils are used as the evidence for the conclusions now insisted on.
What is a transition?
Well all or some or any fossils of all the body types between point a and point b.
A long time. Lots of oppourtunity. So many "kinds" must of existed.
Its up to you to show them. Then we can answer if you have proven ancestry or making a guess.
