The crossword clue "Animals that appear in the fossil record before trees" with the answer "SHARKS" refers to the fact that sharks are among the earliest animals to have appeared in Earth's history, predating the emergence of trees.

Sharks first appeared in the fossil record more than 400 million years ago, during the Silurian period, which is significantly earlier than the first appearance of trees in the fossil record, which occurred around 380 million years ago in the Devonian period.

The crossword clue "Animals that appear in the fossil record before trees" with the answer "JELLYFISH" refers to the fact that jellyfish are among the oldest animals in Earth's history, appearing in the fossil record long before the first trees. Jellyfish first emerged around 500 million years ago, during the Cambrian period, making them some of the earliest multicellular organisms.

Trees, on the other hand, began to appear in the fossil record approximately 380 million years ago during the Devonian period. This significant gap highlights how jellyfish predate trees by a substantial margin, showcasing their ancient lineage and early presence in marine environments.

The crossword clue "Animals that appear in the fossil record before trees" with the answer "TRILOBITES" refers to the fact that trilobites are among the earliest known animals, appearing in the fossil record well before trees. Trilobites were marine arthropods that lived from the Cambrian period to the Permian period, roughly between 520 and 250 million years ago.

They first appeared around 520 million years ago, which is significantly earlier than the emergence of trees, which appeared around 380 million years ago in the Devonian period. This makes trilobites some of the oldest and most ancient animals, predating the first trees by a considerable margin and highlighting their early presence in the Earth's history.

The crossword clue "Animals that appear in the fossil record before trees" with the answer "HORNFISH" refers to the fact that hornfish, like some other ancient fish, appear in the fossil record before trees. Hornfish, a term used to describe certain prehistoric fish with distinctive horn-like projections, existed during periods well before the first trees appeared.

Fossils of these early fish can be traced back to the Silurian and Devonian periods, around 400 to 350 million years ago, which is before the emergence of trees in the Devonian period. This makes hornfish some of the early vertebrate animals, existing long before trees became a significant part of Earth's flora.
