Czatkobatrachus polonicus

Overview

Czatkobatrachus polonicus is an Early Triassic frog relative. Isolated bones are known from Czatkowice 1 in present-day southern Poland. Comparisons of its trunk, slender limbs, and short tail reveal its appearance.^[1]

Key facts

A body can be studied even without a complete articulated skeleton. Researchers compare features of separately discovered bones to interpret their positions. Small fragments provide evidence for large questions.^[1]

Time and place

This Early Triassic material comes from Czatkowice 1 in present-day southern Poland. The Triassic as a whole spans roughly 250–200 million years ago. A 2009 study examined the bones of this ancient frog relative in detail.^[1][2]

The time range describes source context, not the complete duration of this species.

Size, form and skeleton

Trunk bones, slender limbs, and short-tail material assigned to the species have been studied. The author compared isolated regions to propose body connections. The arrangement from trunk to limbs and rear body can be examined in parts.^[1]

Czatkobatrachus polonicus is reconstructed as a small frog relative measuring less than 5 cm from snout to the end of the trunk. A 2009 study estimated this size by comparing several pelvic and limb bones and vertebrae together.^[3]

Habitat and reproduction

How does an early frog relative compare with familiar frogs today? Trunk, limb, and short-tail material each reveals different features. Research places several regions side by side to explore varied body arrangements.^[1]

Fossil discovery

A 2009 paper compiled material of this early frog relative from Poland. It described isolated bones, compared them with other evidence, and discussed their connections. Anatomical features of one small bone lead to questions about the entire body.^[1]

Research questions

How can researchers determine where isolated bones belong? Shape, articulating surfaces, and comparisons with other tetrapods provide clues. Czatkobatrachus shows how comparisons sustain research questions even with incomplete material.^[1]

Observation

Move your gaze from the short trunk to the slender limbs and short rear tail. Considering each region separately reveals the organization of an early frog relative more clearly.^[1]
