9 months, 2 weeks ago9 months, 2 weeks agoThe giant clam is the largest shelled mollusk living today, but squid and octopi are also mollusks, so the size prize goes to Architeuthis, a g<span class=” fw-n lh-22 fz-14 fc-obsidian”>enus of deep-ocean dwelling squid. They can reach a size of 33 feet (roughly the size of a school bus) and weigh more than 400 pounds!</span>

Those are very nice mold/cast fossils of brachiopods, which superficially look like mollusks but belong to a different phylum. They have different symmetry and internal organs. Nice specimens!

3 years, 9 months ago3 years, 9 months agoIt looks modern, because it looks mostly made of bone, with little of no mineralization. If it was from a fossil fish, you might expect it to have more of the bone replaced with rock minerals like silicates.
