Hi! For a geometric abstraction, I created this figure using a graphics application. It looks like a filled half parabola. In geometry, what is it called? Thank you! Dr. T

It doesn't really look like a parabola. But, hey, it's a piece of art that you made so you can call it anything you wish. How about "bloody fingernail"?
Meet Arthur. He goes by "Art" for short.
Arthur is li'l Red Riding Hood'd bf?

Even for the outside, how could you tell whether it is a parabola or part of an ellipse?
