Soft-bodied organisms are generally the most difficult to fossilize because they lack hard parts like bones or shells that are more likely to withstand the conditions necessary for fossilization. Examples include jellyfish, worms, and certain types of fungi, which decompose rapidly after death and leave little to no trace. Environmental factors, such as sedimentation rates and conditions that promote decay, further complicate the fossilization process for these creatures. Consequently, soft-bodied organisms are often underrepresented in the fossil record.
snail
possibly plankton
Man.
human female's
Bones typically fossilize the most. There are some examples of fossilized feathers and hair, but it's rare.
A clam.
Clam shells are quite durable.
A cockroach.
Most of them will eat many living oceanic creature but most of the times the creatures have to be smaller than themselves for the man of war to be able to consume the creature
Some people don't believe this, but most do believe it these days. Not a creature, but a beast! Please define 'most'. I know that most people of my acquaintance do not believe that anyone returns to a living existence on Earth after death.
Reproduction
Most invertebrates do not fossilize because of the lack of bones or exoskeleton. Soft tissue rarely fossilizes. B for PLATO users
