  • 1. Lancelets adults bury themselves into the sediment of the seafloor, all chordate characters present in adults, adults swim by the contraction of a series of muscles along the notochord2. Tunicates larvae swim using the notochord, but adults may be sessile, most chordate characters not present in adults; in adults, water enters through one siphon and leaves through another3. Both Lancelets and Tunicates adults feed with the aid of pharyngeal slits
  • They hypothesized that the transitional fossils were in sedimentary rocks older than 365 million years ago, when the first tetrapods appear in the fossil record.
  • 1. To become a fossil, an animal must remain buried for thousands or millions of years until it (and the layer around it) turns to rock.2. Many fossils remain buried. We can only find them when they are exposed by erosion or excavation.3. To become a fossil, an animal must be quickly and completely buried in ash or sediment before it has a chance to decompose.
  • 1. Notochord-a flexible rod that runs along the anterior-posterior axis, may be associated with a jointed skeleton2. Pharyngeal clefts-grooves that separate pouches along the side of the pharynx, may develop into parts of the ear3. Pharyngeal slits- openings to the outside of the body along the side of the pharynx, may develop into gill slits4. Dorsal, hollow nerve cord- a bundle of nervous tissue running the length of the body, may develop into the brain and spinal cord5. Muscular, post-anal tail- a structure that contains muscles and extends past the anus, may be used to propel some species in water
Lancelets and tunicates are two groups of chordates. Classify each statement as applying to lancelets, tunicates, both lancelets and tunicates, or neither.Drag each item to the appropriate bin.

What is a transitional fossil?
  • The transition occurred gradually over time, so there are many intermediate forms.
  • Transitional fossils have features that are intermediate between ancestors and descendants.
