What is a worm tube fossil?
Tubeworms, as the name suggests, are worms that protect themselves by living in a hard tube which they secrete around their body. They are a hugely successful group in the world’s oceans today and their fossil ancestors are found throughout the Jurassic and Cretaceous rocks of the Jurassic Coast.
What is a tube worm made of?
Worm Tube The tube is made out of a hard substance called chitin, the same material found in the outer skeletons of crabs and shrimp. The tubes protect the worms from predators and the toxic chemicals from the vents. They also serve as an outer skeleton, supporting the worm. A worm can never leave its tube.
What do tube worms look like?
The tube worm looks like a long white tube with an odd bright red nail called a plume or a giant paintbrush. Inside the tube the body of the worm is colorless. The tube worm can grow up to nine feet long and can live 170 to 250 years. The tube worm’s red plume is food for fish, crabs, and other sea creatures.
What do giant tube worms look like?
Giant tube worms can reach 8 feet in length and 1.6 inches in diameter. Giant tube worms have soft, colorless body hidden inside hard tube made of chitin (shells of crustaceans are composed of same substance). Tube offers protection against predators. Giant tube worms do not have eyes, mouth, stomach and legs.
How do I identify my fossil?
Mostly, however, heavy and lightly colored objects are rocks, like flint. Paleontologists also examine the surfaces of potential fossils. If they are smooth and do not have any real texture, they are probably rocks. Even if it is shaped like a bone, if it does not have the right texture then it is probably a rock.
How can you tell if coral is fossilized?
Horn or tooth shape with segments
- Horn corals are the most common type of fossil with a horn shape and segmented ridges. If you can see the top of the fossil, a coral will have a cup-like depression. The cup will have grooves or lines radiating out from the axis.
- Some fossil horns have turned out to be cephalopods.
What do tube worms do?
The tubeworms’ feather-like red plumes act as gills, absorbing oxygen from seawater and hydrogen sulfide from vent fluids. This feat is accomplished by a special type of hemoglobin in their blood that can transport oxygen and sulfide at the same time (human hemoglobin transports only oxygen).
How does the tube worm reproduce?
Giant tube worms reproduce by releasing their eggs into the water to be fertilized. After hatching, the young larvae swim down and attach themselves to rocks. As the larvae develop into tiny worms, they temporarily develop a primitive mouth and gut through which the symbiotic bacteria enter.
What do baby tube worms look like?

How do I find fossils in my yard?
- Look for fossils in sedimentary rock, including sandstone, limestone and shale, preferably where the earth has been cleaved by road cuts, construction sites, rivers or streams.
- fossils and the remains of vertebrate animals (those with a backbone).
- Then, contact your local natural history museum.
