Dataset Card for Graptoloidea Specimens Imaging
Dataset Summary
This dataset offers a detailed examination of Graptoloidea specimens, featuring attributes like image file paths, suborder, infraorder, family (including subfamily), tagged species names, geological stages, mean age values, and locality details (with coordinates and horizon information), complemented by original reference citations for each specimen. It serves as a comprehensive resource for paleontological research, emphasizing morphological and stratigraphic analysis of these ancient colonial animals.
Dataset Preprocessing
This dataset doesn't download the images locally by default. Instead, it exposes URLs to the images. To fetch the images, use the following code (Make sure in the correct environment):
from concurrent.futures import ThreadPoolExecutor
from functools import partial
import io
import urllib
import PIL.Image
from datasets import load_dataset
from datasets.utils.file_utils import get_datasets_user_agent
USER_AGENT = get_datasets_user_agent()
def fetch_single_image(image_url, timeout=None, retries=0):
for _ in range(retries + 1):
try:
request = urllib.request.Request(
image_url,
data=None,
headers={"user-agent": USER_AGENT},
)
with urllib.request.urlopen(request, timeout=timeout) as req:
image = PIL.Image.open(io.BytesIO(req.read()))
break
except Exception:
image = None
return image
def fetch_images(batch, num_threads, timeout=None, retries=0):
fetch_single_image_with_args = partial(fetch_single_image, timeout=timeout, retries=retries)
with ThreadPoolExecutor(max_workers=num_threads) as executor:
batch["image"] = list(executor.map(fetch_single_image_with_args, batch["image"]))
return batch
num_threads = 20
dset = load_dataset('Graptolodiea-Speciemens-Imaging.py')
dset = dset.map(fetch_images, batched=True, batch_size=100, fn_kwargs={"num_threads": num_threads})
Dataset description
Supported Tasks
- Paleontological Analysis and Classification: Utilizing the dataset for detailed classification of Graptoloidea species, including sorting by suborder, infraorder, and family. Fundamental for researchers in paleontology to understand evolutionary trends and species distinctions.
- Age Estimation and Stratigraphic Correlation: Leveraging mean age values and stage data to estimate the geological age of specimens and correlate them with stratigraphic layers. Crucial for geologists and paleontologists in mapping the geological timeline and understanding the Earth's history.
- Geographical Distribution Study: Analyzing locality data to study the geographical distribution and migration patterns of Graptoloidea species. Can reveal insights into ancient ecological conditions and biogeographic events.
- Morphological Analysis: Using the provided specimen images for morphological studies, enabling the identification of unique features and variations within the Graptoloidea order. Important for taxonomic classification and evolutionary studies.
- Data-Driven Paleobiology: Applying machine learning and statistical methods to uncover patterns and relationships in Graptoloidea evolution, diversity, and extinction events.
- Morphometric Analysis: Employing image processing techniques to measure and analyze morphological features of the specimens, such as length, shape, branching patterns, and other key characteristics.
- Virtual Reconstruction and 3D Modeling: Using specimen images to create detailed 3D models of Graptoloidea for virtual reality experiences, aiding in both research and educational endeavors.
- Educational and Outreach Tools: Developing interactive tools and applications for educational purposes, using specimen images to engage and teach students and the public about Graptoloidea and paleontology.
- Crowdsourcing and Citizen Science Projects: Allowing citizen scientists to access and annotate the images, contributing to data collection and analysis efforts.

Dataset Creation
Curation Rationale
The primary objective of curating the Graptoloidea Specimens dataset is to provide a comprehensive and accessible resource for the study and analysis of Graptoloidea, an order of extinct marine colonial organisms. This dataset is intended to support a wide range of scientific endeavors, including paleobiological research, evolutionary studies, and educational purposes in the field of paleontology. By assembling high-resolution images and detailed taxonomic information, the dataset aims to facilitate in-depth investigations into the morphology and classification of these ancient organisms, contributing to a broader understanding of Earth's geological history and biodiversity.
