Connecting Links
- Living + nonliving = virus
- Protozoa + porifera = Proteospongia
- Plant + animal = Euglena
- Protozoa + Metazoa = Xenoturbella + Nemertodema
- Annelida + Mollusca = Neoplina
- Protochordata + Vertebra = Ainiktozoan
- Fish + Land vertebrate = Coelocanthus
- Amphibia + Reptile = Seymouria
- Arthropoda + Annelids = Peripatus
- Bony fish + Amphibia = lung fish
- Fish + tetrapods = Latemaria
- Bird + reptile = archaeopteryx.
- Coerentrate + Platyhelminthes = Ctenoplana
- Echinoderm + Chordate – Balanoglossus
- Reptiles + mammals = Duck Billed Platypus, Spring Ant Eater
- Aquatic + land plants = Fritschiella
Living Fossils
- Limulus – Arthropoda
- Neopline – Mollusca – Nautilus
- Plastasterias – Echinodermata
- Lamprey – Cyclostomata – Chordate
- Latimeria – oldest living fish
- Sphendon – reptilian
- Echidna – Mammalia
- Peripatus – Arthropod
