How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Studying the sensation mechanism that allows birds to locomote with outstanding agility in every livable habitat on earth. Hypothesis testing requires applying novel interdisciplinary approaches. The LSO is deeply embedded within the spinal canal, and so far, there is no currently available imaging facility to test our hypotheses on LSO in-vivo. Therefore we are studying the LSO by combining methods of digital and classical morphology and biomechanical simulation.

Avian ability to agile and precise locomotion in every livable habitat has fascinated researchers for over a century. One explanation for birds' agility is a mechanosensory organ directly integrated into the lower spine in the lumbosacral region. The proximity of the potential mechanosensory organ to the sciatic nerve and its associated motor circu...
Synopsis Birds are diverse and agile vertebrates capable of aerial, terrestrial, aquatic, and arboreal locomotion. Evidence suggests that birds possess a novel balance sensing organ in the lumbosacral spinal canal, a structure referred to as the “lumbosacral organ” (LSO), which may contribute to their locomotor agility and evolutionary success. The...
Hyneria lindae is one of the largest Devonian sarcopterygians. It was found in the Catskill Formation (late Famennian) of Pennsylvania, USA. The current study focuses on the palaeohistology of the humerus of this tristichopterid and supports a low ossification rate and a late ossification onset in the appendicular skeleton. In addition to anatomica...
In order to understand the ecological dimension of the fish-tetrapod transition, which occurred within the tetrapod stem group during the Devonian Period (419-359 million years ago), we need life-history data from transitional forms. Only recently have serious attempts begun to utilize limb-bone histology as a source of such data. Here we present h...
Recently, attempts have been made to utilize limb-bone histology as a source of data for understanding the ecological dimension of the fish-tetrapod transition. Here we present histological life history data from a humerus (ANSP 21483) of Hyneria lindae, a fish member of the tetrapod stem group from the Late Devonian Catskill Formation (Pennsylvani...
