Arthropod - Wikipedia. (uncertain if they are trilobites) Arthropodsɑːr, from Ancient Greek ἄρθρον (arthron) 'joint', and πούς (pous) 'foot' (gen. ποδός)) are invertebrate in the phylum Arthropoda. They possess an exoskeleton with a made of , often calcium carbonate, a metamerically body, and paired jointed appendages.There are a few Cambrian contenders but it is difficult to determine whether these are genuine fossil vertebrates from which most vertebrate characteristics have rotted away or fossils that belong in a more basal position in the tree, with invertebrate chordates (e.g., Cathaymyrus and Metaspriggina; Conway Morris 2008; Shu et al. 1996a).Jun 1, 2022 · No marine invertebrate fossils have been found in these sandstone beds. The Redback-2 core is located in the Redback Gas Field, approximately 30 km southeast of Dongara and 20 km southeast of the Apium-1 core ( Fig. 1B ). Bryozoan fossils occur in many forms, including finger-shaped, fan-shaped, mats, spiralling fans, and massive irregular mounds. Many of the fossils, if examined closely with a magnifying glass, will show the individual pits where the individual bryozoans lived. ...

We all know that invertebrates lack backbones, but the differences among the various types of invertebrates go a lot deeper than that. On the following slides, you'll discover the 31 different groups, or phyla, of invertebrates, ranging from amoeba-like placozoans that stick to the sides of fish tanks to marine animals, like octopuses, that can achieve a near-vertebrate level of intelligence.
