The squid is a marine-dwelling mollusk, a member of the class Cephalopoda (cephalopods). This photo shows a 95-million-year-old squid fossil. There is not the slightest difference between it and present-day specimens. The pigment sac beneath the skin can even be seen in this fossil, and its skeletal structure is identical to those in modern-day squid.If evolutionists" claims were true, then squid should have undergone various changes over the course of millions of years, and by now, various fossil specimens documenting these stages should have been discovered. But every fossil found shows that squid have survived completely unchanged for millions of years.
