Ok, AL; Let's Go See what Wiki has to Say.

You're clutching at straws Mark.
Despite any apparent similarities with the fossil record from the distant past there is nevertheless an evolutionary history for starfish.
http://en.wikipedia.org/wiki/Starfish
There is a huge diverse variety of starfish around today that have all adapted to their particular environment, so finding one that happens to resemble an earlier shape isn't particularly remarkable. We should also consider that the fossil record only shows the spines and calcium hardened parts. If a particular basic shape is what works best then there is no evolutionary diktat that requires it to change anyway.
From your Wiki Article;
"The fossil record for starfish is ancient, dating back to the Ordovician around 450 million years ago, but it is rather poor, as starfish tend to disintegrate after death. Only the ossicles and spines of the animal are likely to be preserved, making remains hard to locate. With their appealing symmetrical shape, starfish have played a part in literature, legend, design and popular culture. They are sometimes collected as curios, used in design or as logos, and in some cultures, despite possible toxicity, they are eaten."
I posted a Picture of one of the Oldest Starfish in the Fossil Record;
What new Anatomy has Appeared, that the Original Starfish Did not Contain?
If they have Looked Exactly like Starfish for supposedly over 450 Million Years;
What do you believe they Mutated From?
A Sand Dollar?
Possibly a Sea Cucumber?
Oh, I know! A Sea urchin, cause they have Spikes, Right?
Or, is the Evolutionary Belief system of "How Starfish Happened", even Less Reasonable Than That?
Let's See;
By the late Paleozoic, the crinoids and blastoids were the predominant echinoderms, and some limestones from this period are made almost entirely from fragments from these groups. In the two major extinction events that occurred during the late Devonian and late Permian, the blastoids were wiped out and only a few species of crinoids survived.[83] Many starfish species also became extinct in these events, but afterwards the surviving few species diversified rapidly within about sixty million years during the Early Jurassic and the beginning of the Middle Jurassic.[7][85] A 2012 study found that speciation in starfish can
occur rapidly. (I'd say, It's almost like they Just Appeared that Way =M=) During the last 6,000 years, divergence in the larval development of Cryptasterina hystera and Cryptasterina pentagona has taken place, the former adopting internal fertilization and brooding and the latter remaining a broadcast spawner.[86]

The majority of the early fossils were sea urchins, probably because their hard tests are easily preserved.
No Way! I almost don't believe I'm Reading this In Wikipedia. LOL!!!
Echinoderms first appeared in the fossil record in the Cambrian. The majority of the early fossils
were sea urchins, (
probably because their hard tests are easily preserved).
The first known asterozoans,
which includes both starfish and brittle stars,
date back to the Ordovician. They were the Somasteroidea, which exhibit characteristics of both groups. Modern starfish and brittle stars probably had a common somasteroid ancestor.[83] Starfish are infrequently found as fossils, possibly because their hard skeletal components separate as the animal decays. However, although starfish fossils are uncommon, there are a few places where accumulations of complete skeletal structures occur, fossilized in place in Lagerstätten — so-called "starfish beds".[84]
I wonder how Old Sand Dollars Are, and if they always have contained that cool Design, on the Top of them...
============================================
Sea Urchin;
I'd Say I'd have to agree with Wikipedia, Sea Urchin to Starfish, is quite an Abrupt Change. What a Mutation!!!
It's an Atheist Miracle!!! LOL!!!
Evolutionists believe in Magic.

The Cambrian (/ˈkæmbriən/ or /ˈkeɪmbriən/) is the first geological period of the Paleozoic Era, lasting from 541.0 ± 1.0 to 485.4 ± 1.9 million years ago (mya) and is succeeded by the Ordovician.
The Ordovician /ɔrdəˈvɪʃən/ is a geologic period and system, the second of six of the Paleozoic Era, and covers the time between 485.4 ± 1.9 and 443.4 ± 1.5 million years ago

Are you telling me that the First Starfish that Ever Lived, Looks just like the Starfish we see Today?
Containing Every Functional anatomical feature, that they did when they first Appeared?

Give Up AL; You have a Religion, a set of beliefs that are not based On Observed Truth (Science).
All Right Kids, here she Is!!!
Supposedly 430 Million years old, and Still contains all the Same Anatomical Structures that Modern Starfish do, It's "Australaster Giganteus", Otherwise known as, "Hey Look at that Cushion Star like 430 MYO FOSSIL~"
